Families in the Shadow of Cancer

The aims of this study were 1) to clarify the factors associated with family functioning in cancer patient’s families with dependant children, 2) to examine children’ mental health when they are exposed to parental cancer, 3) to explore the subjective experience of having cancer during pregnancy, and finally, 4) to describe the implementation of a childcentred family intervention for cancer patients’ families with dependant children in an adult oncology setting. The study groups were collected between May 1st 2002 and April 30th 2004. They consisted of one European group collected from six different countries (N = 381) and two Finnish clinical groups (N = 85 and N = 2). The first Finnish clinical group of 85 cancer patient families with dependant children included a sub-sample of 54 families with children aged 11-17 years. The second Finnish clinical group consisted of two pregnant cancer patients. Additionally, a control group (N = 59) consisting of a sub-sample of 49 families with children aged 11-17 years was used. Quantitative methods (FAD, BDI, YSR, SOC, SF-8) and qualitative methods (observation, interviews, diaries, videotapes) were used exclusively and/or in combination. The results can be summarised as follows: 1) cancer “per se “ did not impair family functioning, children’s mental health, early interaction between ill mothers and their infant, 2) maternal depression or the ill parent’s depression were significantly associated with impairment in family functioning, 3) the individual’s good sense of coherence was associated with improvement in family functioning, and 4) a child-centred family intervention, which aims to give space for elaborating on cancer in the family, validates the sense of coherence and children’s feelings, and promotes open communication was welcomed. It is important to note that in the European study group, the prevalence of depression was 35 % (BDI > 16) among ill mothers, and 28% among healthy mothers, 28% among ill fathers, and 13% among healthy fathers. Early screening and effective treatment of depression in cancer patients and their partners is of paramount importance for the mental health of children and the well-being of the family. Pregnant cancer patients are in need of psychosocial support.

L'insatisfaction des besoins en soins de support chez les patients atteints d'un cancer du poumon en fonction du genre, de l'âge et du tabagisme : étude descriptive corrélationnelle transversale

Les patients atteints d'un cancer du poumon souffrent de différents troubles physiques et psychosociaux sévères causés par la maladie et son traitement. Ces troubles engendrent plusieurs besoins en soins de support chez les patients. Afin de satisfaire leurs besoins et de leur offrir la meilleure qualité de soins possible, l'identification des besoins en soins de support des patients devient primordiale. But : Le but de l'étude est, dans un premier temps, d'identifier et de décrire les besoins insatisfaits en soins de support pour les patients souffrant d'un cancer du poumon pendant la phase de chimiothérapie dans un Centre Hospitalier Universitaire en Suisse (CHU). Dans un second temps, le but de l'étude est également d'explorer l'éventuelle existence de différences quant au degré d'insatisfaction, tel qu'exprimé par les patients, notamment en fonction de l'âge, du genre et du tabagisme des patients. Cadre théorique : La présente étude se base sur la théorie du déficit d'auto-soin de Dorothea Orem. Méthode : Le travail de recherche s'est basé sur un devis descriptif corrélationnel transversal. L'échantillon, composé de 26 patients atteints d'un cancer du poumon, a été recruté selon la méthode non probabiliste accidentelle dans le service d'oncologie ambulatoire du CHU. Le recueil des données a été effectué à travers deux questionnaires auto-administrés aux patients (Supportive Care Needs Survey Short Form 34 et un questionnaire socio-démographique). Les données médicales ont été recueillies par l'étudiant chercheur à travers la consultation des dossiers médicaux. Résultats : Les résultats montrent que les besoins les plus insatisfaits chez les patients se regroupent surtout autour des besoins liés aux aspects psychologiques et physiques/vie quotidienne. Les patients expriment aussi un degré d'insatisfaction par rapport aux besoins en information ainsi qu'aux soins et au soutien prodigués par les soignants. Les deux besoins le plus fréquemment (65,38 %) exprimés comme insatisfaits par les patients ont été : « être informé de ce que vous pouvez faire vous-même pour aller mieux » et « l'incertitude face à l'avenir ». Les différences des degrés d'insatisfaction, tel qu'exprimés par les patients, en fonction de l'âge, du genre du tabagisme ont permis de poser des hypothèses quant aux relations entre ces variables et le degré d'insatisfaction : les femmes seraient plus insatisfaites de toutes les dimensions liées aux besoins en soins de support ; les patients d'âge égal ou supérieur à 65 ans seraient plus insatisfaits quant aux besoins physiques/vie quotidienne, psychologiques et de soutien; les patients d'âge inférieur à 65 ans seraient plus insatisfaits quant aux besoins liés à la sexualité; les non-fumeurs avant le diagnostic seraient plus insatisfaits quant aux besoins physiques/vie quotidienne, d'information et sexuels ; les patients qui arrêtent de fumer après le diagnostic seraient plus insatisfaits quant aux besoins physique/vie quotidienne, psychologique et de soutien. Conclusion : Cette étude met en évidence le fait que, pendant la phase de chimiothérapie, les patients atteints d'un cancer du poumon expriment de l'insatisfaction par rapport à plusieurs besoins en soins de support. Afin d'améliorer la qualité des soins et de mieux répondre aux besoins des patients, les infirmières et les équipes interdisciplinaires présentes au sein des services d'oncologie du CHU sont appelés à prendre en considération l'insatisfaction exprimée par les patients.

"Hit the primary": A paradigm shift in the treatment of metastatic prostate cancer?

Patients with metastatic prostate cancer (PC) represent a heterogeneous group with survival rates varying between 13 and 75 months. The current standard treatment in this setting is hormonal therapy, with or without docetaxel-based chemotherapy. In the era of individualized medicine, however, maximizing treatment options, especially in long-term surviving patients with limited disease burden, is of capital importance. Emerging data, mainly from retrospective surgical series, show survival benefits in men diagnosed with metastatic PC following definitive therapy for the prostate. Whether the irradiation of primary tumor in a metastatic disease might improve the therapeutic ratio in association with systemic treatments remains investigational. In this scenario, modern radiation therapy (RT) can play a significant role owing to its intrinsic capability to act as a more general immune response modifier, as well as to the potentially better toxicity profile compared to surgery. Preclinical data, clinical experience, and challenges in local treatment in de novo metastatic PC are reviewed and discussed.

Adjuvant Fluorouracil, Leucovorin, and Oxaliplatin in Stage II to III Colon Cancer: Updated 10-Year Survival and Outcomes According to BRAF Mutation and Mismatch Repair Status of the MOSAIC Study.

PURPOSE: The MOSAIC (Multicenter International Study of Oxaliplatin/Fluorouracil/Leucovorin in the Adjuvant Treatment of Colon Cancer) study has demonstrated 3-year disease-free survival (DFS) and 6-year overall survival (OS) benefit of adjuvant oxaliplatin in stage II to III resected colon cancer. This update presents 10-year OS and OS and DFS by mismatch repair (MMR) status and BRAF mutation. METHODS: Survival actualization after 10-year follow-up was performed in 2,246 patients with resected stage II to III colon cancer. We assessed MMR status and BRAF mutation in 1,008 formalin-fixed paraffin-embedded specimens. RESULTS: After a median follow-up of 9.5 years, 10-year OS rates in the bolus/infusional fluorouracil plus leucovorin (LV5FU2) and LV5FU2 plus oxaliplatin (FOLFOX4) arms were 67.1% versus 71.7% (hazard ratio [HR], 0.85; P = .043) in the whole population, 79.5% versus 78.4% for stage II (HR, 1.00; P = .980), and 59.0% versus 67.1% for stage III (HR, 0.80; P = .016) disease. Ninety-five patients (9.4%) had MMR-deficient (dMMR) tumors, and 94 (10.4%) had BRAF mutation. BRAF mutation was not prognostic for OS (P = .965), but dMMR was an independent prognostic factor (HR, 2.02; 95% CI, 1.15 to 3.55; P = .014). HRs for DFS and OS benefit in the FOLFOX4 arm were 0.48 (95% CI, 0.20 to 1.12) and 0.41 (95% CI, 0.16 to 1.07), respectively, in patients with stage II to III dMMR and 0.50 (95% CI, 0.25 to 1.00) and 0.66 (95% CI, 0.31 to 1.42), respectively, in those with BRAF mutation. CONCLUSION: The OS benefit of oxaliplatin-based adjuvant chemotherapy, increasing over time and with the disease severity, was confirmed at 10 years in patients with stage II to III colon cancer. These updated results support the use of FOLFOX in patients with stage III disease, including those with dMMR or BRAF mutation.

International comparison of the German evidence-based S3-guidelines on the diagnosis and multimodal treatment of early and locally advanced gastric cancer, including adenocarcinoma of the lower esophagus.

BACKGROUND: Clinical guidelines are essential in implementing and maintaining nationwide stage-specific diagnostic and therapeutic standards. In 2011, the first German expert consensus guideline defined the evidence for diagnosis and treatment of early and locally advanced esophagogastric cancers. Here, we compare this guideline with other national guidelines as well as current literature. METHODS: The German S3-guideline used an approved development process with de novo literature research, international guideline adaptation, or good clinical practice. Other recent evidence-based national guidelines and current references were compared with German recommendations. RESULTS: In the German S3 and other Western guidelines, adenocarcinomas of the esophagogastric junction (AEG) are classified according to formerly defined AEG I-III subgroups due to the high surgical impact. To stage local disease, computed tomography of the chest and abdomen and endosonography are reinforced. In contrast, laparoscopy is optional for staging. Mucosal cancers (T1a) should be endoscopically resected "en-bloc" to allow complete histological evaluation of lateral and basal margins. For locally advanced cancers of the stomach or esophagogastric junction (≥T3N+), preferred treatment is preoperative and postoperative chemotherapy. Preoperative radiochemotherapy is an evidence-based alternative for large AEG type I-II tumors (≥T3N+). Additionally, some experts recommend treating T2 tumors with a similar approach, mainly because pretherapeutic staging is often considered to be unreliable. CONCLUSIONS: The German S3 guideline represents an up-to-date European position with regard to diagnosis, staging, and treatment recommendations for patients with locally advanced esophagogastric cancer. Effects of perioperative chemotherapy versus chemoradiotherapy are still to be investigated for adenocarcinoma of the cardia and the lower esophagus.

Treatment of cancer with oral drugs: a position statement by the Spanish Society of Medical Oncology

Cancer treatment involves the participation of multiple medical specialties and, as our knowledge of the disease increases, this fact becomes even more apparent. The degree of multidisciplinarity is determined by several factors, which include the severity and type of disease, the increasing diversity in the available pharmacological and non-pharmacological therapies, and the range of specialists involved in cancer therapy, such as medical oncologists, radiotherapists, gynecologists, gastroenterologists, urologists, surgeons, and pneumologists, among others. Across Europe, the situation of cancer care can be variable due to the diversity of health systems, differences in drug reimbursement, and the degree of establishment of Medical Oncology as a medical specialty in the European Union states.

Les besoins en soins de support chez les patients en phase d'un traitement ambulatoire, suivant l'annonce d'un diagnostic de cancer : étude descriptive transversale

Problématique L'incidence du cancer ne cesse d'augmenter dans les pays occidentaux et en Suisse, en constituant la deuxième cause de mortalité après les maladies cardiovasculaires. Si d'une part, les différents traitements oncologiques ont le potentiel de guérir certains cancers et d'augmenter l'espérance de vie des personnes concernées, ils sont associés à de multiples problèmes physiques et psychosociaux. De même, l'annonce de la maladie provoque une fragilité émotionnelle et sociale et la phase de traitement qui suit le diagnostic de cancer est souvent associé à des besoins psychologiques et d'information élevés. But Cette étude vise à décrire les besoins en soins de support insatisfaits chez les patients nouvellement diagnostiqués d'un cancer, au cours d'un traitement ambulatoire dans un Hôpital Cantonal de la Suisse. Elle vise également à identifier les associations entre les besoins en soins de support insatisfaits et les caractéristiques sociodémographiques et médicales. Méthode Cette étude corrélationnelle descriptive a été conduite auprès de 67 patients nouvellement atteints d'un cancer primaire ou d'une récidive, recrutés selon un échantillonnage non probabiliste par convenance consécutive. Le questionnaire auto-administré comprenait le Supportive Care Needs Survey Short Form 34 et un questionnaire sur des données sociodémographiques. Les données médicales ont été collectées par les chercheurs à travers les dossiers médicaux. Résultats Les trois besoins exprimés comme les plus insatisfaits étaient « la peur que le cancer se propage » (48,5%), « l'incertitude face à l'avenir » (45,4%) et « vos préoccupations face à l'incertitude de vos proches » (43,9%). Nous constatons une insatisfaction plus élevée des besoins psychologiques (M: 32,6 ; ET: 20,4) et des besoins d'information (M: 29,3 ; ET: 17,5) par rapport aux autres dimensions de besoins. À propos des caractéristiques associées a un plus haut niveau de besoins insatisfaits, nous trouvons qu'être plus jeune (29-56 ans) ou âgés de > 72 ans est positivement associé aux besoins insatisfaits du domaine psychologique (F = 3,50 ; p = 0,02) et de l'information/système de santé (F = 3,48 ; p = 0,02). Le jeune âge est aussi associé à plus de besoins dans le domaine sexuel (F = 2,85 ; p = 0,04). Il semble exister une association négative entre le niveau d'instruction et le degré d'insatisfaction des besoins psychologiques (F = 2,92, p = 0,06). Être retraité coïncide avec un plus grand degré d'insatisfaction dans les besoins physiques et des activités de la vie quotidienne (F = 4,64 ; p = 0,013). Finalement, avoir un moins bon état général est relié à plus de besoins physiques et de besoins issus du domaine des activités de la vie quotidienne (t = -2,85 ; p = 0,005). Conclusions Les présents résultats concordent avec les études antérieures. Cette étude a la particularité d'avoir identifié les besoins insatisfaits durant la phase de traitement qui suit l'annonce du diagnostic, sans se restreindre à une maladie cancéreuse spécifique, ce qui a été peu effectué auparavant. Les chercheurs infirmiers devraient poursuivre, en collaboration avec d'autres professionnels de la santé, les recherches visant le développement d'approches efficaces pour réduire les besoins insatisfaits chez des personnes atteintes de maladies cancéreuses.

The forced adoption of a fast-track appraisal process for a breast cancer treatment in UK

Trastuzumab (Herceptin ®, Roche) is approved in UK for the treatment of the metastatic breast cancer since 2001. As of 2005, concomitantly with the publication of 3 studies that showed it produces a 50% reduction of the recurrence rates of breast cancer, trastuzumab started to be prescribed in the earlt adjuvant treatrnent of this disease. Und June 2006, trastuzumab did not have both: 1) regulatory approval and 2) NICE [National Institute for Health and Clinical Excellence] recommendation for the use in early stages of breast cancer. During the period until June 2006, the trastuzumab use in those patients was not reimbursed and because the cost of trastuzumab is equal with the yearly UK average income, most of patients could not self fund their treatrnent. Before the publication of the final NICE guidance, the new data of trastuzumab in early breast cancer raised enormous patient and professional interest and expectations. A great volume of public and professional pressure was generated to transcend a system by which Primary Care Trusts can reimburse a treatment only after a formal guidance was issued. This paper draw on a case study depicting and analyzing the process by which regulatory approval and NICE recommendations were achieved in a record time and how trastuzumab became a standard treatment on early adjuvant breast cancer. According to the data we gathered in this work we were witnessing one of the fastest processes of adoption of a health care technology since the creation of NICE, in 1999. This study addresses the following research question: How and why does the adoption pattern of trastuzumab differ from the rational decision-making model of the reimbursement process in UK?

Oncobiguanides: Paracelsus" law and nonconventional routes for administering diabetobiguanides for cancer treatment

The dose makes the poison, the common motto of toxicology first expressed by Paracelsus more than 400 years ago, may effectively serve to guide potential applications for metformin and related biguanides in oncology. While Paracelsus' law for the dose-response effect has been commonly exploited for the use of some anti-cancer drugs at lower doses in non-neoplastic diseases (e.g., methotrexate), the opposite scenario also holds true; in other words, higher doses of non-oncology drugs, such as anti-diabetic biguanides, might exert direct anti-neoplastic effects. Here, we propose that, as for any drug, there is a dose range for biguanides that is without any effect, one corresponding to"diabetobiguanides" with a pharmacological effect (e.g., insulin sensitization in type 2 diabetes, prevention of insulin-dependent carcinogenesis, indirect inhibition of insulin and growth factor-dependent cancer growth) but with minimal toxicity and another corresponding to 'oncobiguanides' with pharmacological (i.e., direct and strong anticancer activity against cancer cells) as well as toxic effects. Considering that biguanides demonstrate a better safety profile than most oncology drugs in current use, we should contemplate the possibility of administering biguanides through non-conventional routes (e.g., inhaled for carcinomas of the lung, topical for skin cancers, intravenous as an adjunctive therapy, rectal suppositories for rectal cancer) to unambiguously investigate the therapeutic value of high-dose transient biguanide exposure in cancer. Perhaps then, the oncobiguanides, as we call them here, could be viewed as a mechanistically different type of anti-cancer drugs employed at doses notably higher than those used chronically when functioning as diabetobiguanides

Treatment-related renal side-effects in pediatric cancer patients

Background: The long-term side-effects of cancer treatments are of growing importance, since the number of pediatric cancer survivors has considerably increased. Renal side-effects should be noted early to prevent further deterioration. Renal dysfunction may also develop long after cancer treatment. Easy and reliable methods for assessing renal function are needed. Aims: The aims were to find the mechanisms behind methotrexate-induced renal damage by studying renal tubular cells (LLC-PK1cells), and to evaluate the usefulness of laboratory tests in assessing glomerular function in pediatric cancer patients by comparing an isotope clearance method with alternative methods. The aim was also to study the long-term effects of bone marrow transplantation (BMT) and high-dose methotrexate (HD-MTX) treatment in renal function. Results: Methotrexate induced time-dependent renal tubular cell swelling and cell death. In patients treated with HD-MTX a significant decrease in GFR was noted after a follow-up time of one to ten years. One year after BMTthe GFR was reduced, especially in patients treated with total body irradiation (TBI). GFR recovered slightly but remained stable thereafter. In glomerular function assessment the serum cystatin C (cysC) concentration showed a significant association with GFR measured by the isotope method. Conclusions: Methotrexate induced acute damage in renal tubular cells. In assessing GFR the isotope method still remains the method of choice, but the assay of cystatin C was the most reliable of other alternatives. Long-term follow-up of renal function is needed in BMT patients and patients treated with HD-MTX.

Estimation of lung cancer diagnosis and treatment costs based on a patient-level analysis in Catalonia (Spain)

Background: Assessing of the costs of treating disease is necessary to demonstrate cost-effectiveness and to estimate the budget impact of new interventions and therapeutic innovations. However, there are few comprehensive studies on resource use and costs associated with lung cancer patients in clinical practice in Spain or internationally. The aim of this paper was to assess the hospital cost associated with lung cancer diagnosis and treatment by histology, type of cost and stage at diagnosis in the Spanish National Health Service. Methods: A retrospective, descriptive analysis on resource use and a direct medical cost analysis were performed. Resource utilisation data were collected by means of patient files from nine teaching hospitals. From a hospital budget impact perspective, the aggregate and mean costs per patient were calculated over the first three years following diagnosis or up to death. Both aggregate and mean costs per patient were analysed by histology, stage at diagnosis and cost type. Results: A total of 232 cases of lung cancer were analysed, of which 74.1% corresponded to non-small cell lung cancer (NSCLC) and 11.2% to small cell lung cancer (SCLC); 14.7% had no cytohistologic confirmation. The mean cost per patient in NSCLC ranged from 13,218 Euros in Stage III to 16,120 Euros in Stage II. The main cost components were chemotherapy (29.5%) and surgery (22.8%). Advanced disease stages were associated with a decrease in the relative weight of surgical and inpatient care costs but an increase in chemotherapy costs. In SCLC patients, the mean cost per patient was 15,418 Euros for limited disease and 12,482 Euros for extensive disease. The main cost components were chemotherapy (36.1%) and other inpatient costs (28.7%). In both groups, the Kruskall-Wallis test did not show statistically significant differences in mean cost per patient between stages. Conclusions: This study provides the costs of lung cancer treatment based on patient file reviews, with chemotherapy and surgery accounting for the major components of costs. This cost analysis is a baseline study that will provide a useful source of information for future studies on cost-effectiveness and on the budget impact of different therapeutic innovations in Spain.

Surgical Treatment of Colorectal Cancer. Controversial Issues

Aims: This study was carried out to evaluate surgical treatment of colorectal cancer (CRC) with special interest in present status and controversial issues: stenting as a palliative procedure for metastasized CRC (I), duration of thromboprophylaxis after the surgical treatment of CRC (II), treatment of the increasing population of elderly people (III) and the quality of life (QoL) after surgery for rectal cancer with special reference to pelvic floor dysfunction (IV). Materials and methods: The material consisted of patients with CRC operated on at Turku University Hospital between 2003 and 2008. In study II the data was collected retrospectively from electronic archives. In other studies the follow-up data was collected at postoperative control visits. In study IV the RAND-36 standardized questionnaire and additional questions assessing urinary, sexual and anorectal dysfunction were used. Results: The results of the current study showed that self-expanding metallic stents provided an alternative to palliative surgery in the treatment of obstructive CRC. Low molecular heparin given s.c. for a median of 11 days until hospital discharge seemed to provide sufficient thromboprophylaxis after surgery. With preoperative selection elderly patients with rectal cancer were suitable for major surgery for rectal cancer with morbidity and mortality rates comparable to those in younger patients. There was no difference between preoperative and one year postoperative general QoL for operated rectal cancer patients. Postoperative pelvic dysfunction was associated with an impaired QoL in some dimensions. Conclusions: Many individual factors regarding the patient and the disease must be taken into account when making treatment decisions in CRC to ensure successful treatment of CRC, patient satisfaction and QoL.

Cassava starch extraction effluent treatment in a one phase tubular horizontal pilot reactor with support medium

The cassava starch industries generate a large volume of wastewater effluent that, stabilized in ponds, wastes its biogas energy and pollutes the atmosphere. To contribute with the reversion of this reality, this manipueira treatment research was developed in one phase anaerobic horizontal pilot reactor with support medium in bamboo pieces. The reactor was excavated into the ground and sealed with geomembrane in HDPE, having a volume equal to 33.6 m³ and continuous feeding by gravity. The stability indicators were pH, volatile acidity/total alkalinity ratio and biogas production. The statistical analyses were performed by a completely randomized design, with answers submitted to multivariate analysis. The organical loads in COD were 0.556; 0.670; 0.678 and 0.770 g L-1 and in volatile solids (VS) of 0.659; 0.608; 0.570 and 0.761 g L-1 for the hydraulic retention times (HRT) of 13.0; 11.5; 10.0 and 7.0 days, respectively. The reductions in COD were 88; 80; 88 and 67% and for VS of 76; 77; 65 and 61%. The biogas productions relatively to the consumed COD were 0.368; 0.795; 0.891 and 0.907 Lg-1, for the consumed VS of 0.524; 0.930; 1.757 and 0.952 Lg-1 and volumetric of 0.131; 0.330; 0.430 and 0.374 L L-1 d-1. The reactor remained stable and the bamboo pieces, in visual examination at the end of the experiment, showed to be in good physical conditions.
