Neoadjuvant chemotherapy in Albinos with locally advanced skin cancer at a Blantyre Hospital: - Case Series

Albinism in Africa remains a public health concern with increasing numbers of advanced skin cancer in this population at presentation. There are challenges with availability of Radiotherapy (RT) units in Africa which is an important modality for controlling loco-regional disease alone or in combination with surgery. Proposed chemotherapy regimens have not been well validated through Randomized Controlled Trials thus posing difficulties for standard of care for units that do not have access to functional RT facilities. Malawi is one such country without radiotherapy. Case summary Seven patients with locally advanced skin cancer were seen in the adult oncology unit at Queen Elizabeth Central Hospital in Blantyre (QECH), Malawi between 2010 and 2013. QECH is one of the teaching hospitals in the country. All were subjected to neo-adjuvant chemotherapy. The primary treatment aim was cyto-reduction followed by surgery whilst the secondary outcome was general symptom control. Three patients achieved complete responses of which two underwent resection and a pectoralis major myocutaneous flap. One had a near complete response and three showed partial responses. Conclusion Neo-adjuvant chemotherapy may be a possible.

A review of patients with advanced cervical cancer presenting to palliative care services at Queen Elizabeth Central Hospital in Blantyre, Malawi

Background Cervical cancer is the commonest cancer affecting women in Malawi, which has the highest rate of this disease in the world. Most cases are diagnosed at an advanced stage. Aim To describe the symptom burden, palliative care interventions, and outcomes of cervical cancer patients who entered care at Tiyanjane Clinic in Blantyre, Malawi, between January and December 2012. Methods We reviewed the case files of 72 patients presenting to our hospital-based palliative care service over one year. Results The mean age was 49.5 years. Twenty-six patients (36%) were HIVpositive and the majority of these (n = 22; 85%) were on antiretroviral medication at presentation to palliative care. Pain (n = 66; 92%), vaginal discharge (n = 44; 61%), and unpleasant odour (n = 37; 51%) were commonly reported. Over a third of patients (n = 26; 36%) reported pain in two or more sites. Fourteen patients (19%) reported vaginal bleeding. Spousal breakdown (through widowhood or divorce) was noted in over half (n = 41; 57%) of all cases. Pain relief was provided to 69 (96%) of the patients (morphine to 40 patients; 56%). Common interventions provided included metronidazole tablets (used vaginally), sanitary items, and counselling. At the end of the study period, 18 patients (25%) were still under the care of palliative services. Conclusions Access to medications such as morphine, metronidazole and tranexamic acid can improve quality of life, even when radiotherapy is limited. Health care teams require necessary skills and training, including how to perform a comprehensive assessment, with an emphasis on the provision of psychosexual counselling, to assist with the complexity of symptoms occurring in this vulnerable group.

Clinical efficacy of paclitaxel in the treatment of mid-stage and advanced malignant gastric cancer, and effect of nursing interventions

Purpose: To investigate the clinical efficacy of paclitaxel combined with additional chemotherapy for mid-stage and advanced malignant tumors, and the benefits afforded by scientific nursing. Methods: Patients with mid-stage and advanced gastric cancer were randomly divided into test and control groups. Control group was given intravenous chemotherapy (400 mg/m2 fluorouracil and 2500 mg/m2 cisplatin) and nursed conventionally, while the test group was additionally treated with 80 mg/m2 paclitaxel and underwent special scientific nursing. Clinical effects and changes in the rates of apoptosis and cell proliferation were recorded. The effect of applying scientific nursing on therapeutic outcomes was also evaluated. Results: The overall rate of treatment effectiveness, clinical control rate, mean apoptosis and proliferation rates in the test group were 56.40, 92.30, (7.10 ± 3.17 and 28.70 ± 3.22 %, respectively, while, in the control group, the values were 38.50, 64.10, 25.40 ± 2.67 and 32.60 ± 2.93 %, respectively. The differences were all statistically significant (p < 0.05). In terms of nursing efficacy, the test group had a lower pain score and higher quality-of-life scores (Karnofsky performance status score) than control group. There was no significant difference in the incidence of adverse reactions between the two groups (p > 0.05). Conclusion: Paclitaxel has a significant effect when used to treat mid-stage and advanced gastric cancer. Moreover, additional nursing not only enhances the therapeutic effect but also improves prognosis and quality-of-life.

Histologic response after neoadjuvant chemoradiotherapy in locally advanced rectal adenocarcinoma: experience from Sudan.

Background: Locally advanced rectal cancer can be down staged by neoadjuvant therapy and the resultant tumor response can be quantified histologically. This study aimed to assess pathological response of neoadjuvant chemoradiation in patients with locally advanced rectal cancers treated in Wad Medani Teaching Hospital (WMTH) and National Cancer Institute (NCI), Wad Medani, Sudan. Patients and Methods: A total of 36 consecutive patients with locally advanced rectal cancer that were managed in WMTH and NCI during the period from 2006-2011 were reviewed. Preoperative pelvic radiotherapy was delivered. Total of 46 Gray were delivered concurrently with 5- fluorouracil (5-FU) on the first and last week of radiation. Total mesorectal excision of the rectal tumour either by anterior or abdominoperineal resections was planned at 6-8 weeks from completion of preoperative treatment. The pathological response to therapy was assessed by histopathology examination of the surgical specimen. Results: Initial clinical staging of patients revealed 58.3% of them were stage T3/T4N2M0 and 41.7% were stage T3N0M0. Down-staging to stage T1/T2N0M0 was found in 36.1% and stage T3N0M0 in 30.6%. No response was seen in 8.3% of cases with stage T3/T4N2M0 while complete clinical response (no residual) was seen in 25.0%. Complete histological response was observed in 13.8%. Positive lymph-nodes metastasis was confirmed in 8.3% of cases. Conclusion: Neoadjuvant chemoradiation is a reasonable option for cases of rectal cancer and deserves further evaluation.

Outcome of childhood malignancies at the University of Port Harcourt Teaching Hospital: a call for implementation of palliative care.

Background: Cancers in children are yet to be recognised as an important cause of childhood morbidity and mortality in developing countries where more than 70% of the world annual cases occur. Despite the limited resources and whatever the projected outcome, children with cancer need treatment, be it curative or palliative. Objectives: To determine outcome of cancers in children at the UPTH; identify factors that influence outcome, highlight the need for palliative care. Method: A retrospective study of cases of childhood malignancies admitted into Paediatric Oncology unit of UPTH over a two year period. Clinical profile of patients and outcome were analyzed using SPSS version 20.0. Results: Sixty cases were analysed: 35(58.3%) males, 25(41.7%) females giving a M:F ratio of 1.4:1. Under-fives constituted 55%. Twenty-seven (45%) patients presented within 4 weeks of onset of symptoms. Median duration of symptoms before presentation was 8 weeks while 36 (60%) had metastatic disease at diagnosis. Twenty patients (33.3%) defaulted with or without specific treatment. Mortality was recorded in 26(43.4%) of cases. Conclusion: There were more cases of cancer amongst under-fives with male preponderance. Late presentation, financial constraints and high default rate were contributory factors to poor outcome in most cases. Lack of palliative care left many families to face their sufferings.

The Role of Epstein-Barr Virus LMP-1 Immunohistochemical Staining in Childhood Hodgkin Lymphoma

Background: There are a few published studies about prognostic markers of Epstein-B virus (EBV) related to outcomes in pediatric Hodgkin Lymphoma (HL). Objectives: We aimed to investigate the prognostic value and effect of EBV on survival by using biopsy materials in children and adolescents diagnosed with HL. Patients and Methods: EBV LMP-1 expression was examined using immunohistochemical methods in 58 tumor samples. Clinical features, overall survival (OS) and failure free survival time (FFS) were compared between EBV LMP-1 positive and negative patients. Results: In 20 (35%) patients tumors were LMP-1 positive. When compared with patients above 10 years old, EBV LMP-1 was often positive in patients under 10 years old (30% vs. 70%, P = 0.02). In our most cases having B symptoms and advanced stage, EBV positiveness in Hodgkin Reed-Stenberg cells (H-RS) was not a significant determinant for survival (P = 0.78). Half of the past clinical trials in childhood HL reported longer survival rates in EBV LMP-1 positive patients. In some trials similar to our results there was no significant relationship between EBV and prognosis. Conclusions: The reason of diminished EBV positiviness may be related to technical methods such as not using immunohistochemical and in situ hybridization for EBER antigen but in laboratory conditions painting of control tissues with EBV impair this probability. In addition, cases enrolled to our study were living in Istanbul where social and economical factors are improved rather than generally.
