Effectiveness of core stability exercises and recovery myofascial release massage on fatigue in breast cancer survivors: a randomized controlled clinical trial.

The purpose of the present paper was to evaluate the effects of an 8-week multimodal program focused on core stability exercises and recovery massage with DVD support for a 6-month period in physical and psychological outcomes in breast cancer survivors. A randomized controlled clinical trial was performed. Seventy-eight (n = 78) breast cancer survivors were assigned to experimental (core stability exercises plus massage-myofascial release) and control (usual health care) groups. The intervention period was 8 weeks. Mood state, fatigue, trunk curl endurance, and leg strength were determined at baseline, after the last treatment session, and at 6 months of followup. Immediately after treatment and at 6 months, fatigue, mood state, trunk curl endurance, and leg strength exhibited greater improvement within the experimental group compared to placebo group. This paper showed that a multimodal program focused on core stability exercises and massage reduced fatigue, tension, depression, and improved vigor and muscle strength after intervention and 6 months after discharge.

Effectiveness of the bevacizumab-irinotecan regimen in the treatment of recurrent glioblastoma multiforme: Comparison with other second-line treatments without this regimen.

A retrospective cohort study was conducted to analyse the effectiveness of bevacizumab and irinotecan (BVZ/CPT-11) as a second-line treatment in patients with primary glioblastoma multiforme (GBM) in comparison with a control group that were not administered BVZ/CPT-11 at the first recurrence. The difference in overall survival (OS) between the two groups was used as a predictor of effectiveness. OS was calculated according to prognostic factors and gender. A total of 28 and 32 patients were enrolled in the BVZ/CPT-11 cohort and control group, respectively. The median OS was 17.94 months (95% CI, 14.91-20.96) in the BVZ/CPT-11 treatment cohort and 10.97 months (95% CI, 7.65-14.30) in the control cohort. The results obtained on the effectiveness of BVZ/CPT-11 treatment in patients with primary GBM are consistent with data from previous studies. No significant differences were identified in OS based on prognostic factors; therefore, the latter cannot be used to select patients who would incur the greatest benefits from BVZ/CPT-11 treatment.

Compliance with dietary and nutrient recommendations in the European Prospective Investigation into Cancer and Nutrition (EPIC)-Granada cohort at recruitment

BACKGROUND: The overall intake of energy and nutrients in the Granada EPIC-cohort (European Prospective Investigation into Cancer and Nutrition) is examined in order to assess compliance with the Spanish Nutritional Objectives (NO) and the Recommended Intakes (RI). METHODS: During recruitment (1992-1996), 7,789 participants, aged 35-69, were asked about diet through a validated diet history questionnaire. Nutrient intake is compared to the NO and RI that were valid at that time. Risk of inadequate intake is estimated as the percentage of the sample with intakes: ≤ 1/3 RI (high risk), ≤ 2/3 RI- > 1/3 RI (moderate risk), ≤ RI- > 2/3 RI, > RI. Differences in intakes have been analyzed by sex and age, and by smoking status and BMI. RESULTS: The daily intake of nutrients did not meet the NO as the total contribution of energy from proteins and fats exceeded these guidelines. Whilst intake of most nutrients was above the RI, the amount of iron, magnesium and vitamins D and E provided by the diet was not enough to meet the RI: in women aged 20-49 years, about 55% were at moderate risk for iron inadequacy, and a 20% of women for magnesium. Both sexes were at high risk of inadequacy for vitamin D, although sunlight exposure may supply adequate amounts. Never smokers showed a higher compliance to the NO. CONCLUSION: At recruitment, the nutrient profile of the diet was unbalanced. The observed nutrient inadequacy for iron, magnesium and vitamin E might be attributed to inappropriate dietary habits, and may have implications for future disease risk.

Prevalence of diabetes in a cancer population in a Malaga hospital.

BACKGROUND There are multiple risk factors for cancer, including obesity, sedentary lifestyle, diabetes (DM). Hormon Insulin is a growth factor that promotes cellular differentiation. AIMS The aim of our study is to observe impaired glycaemia in cancer population compared with control. METHODS We studied the prevalence of diabetes (DM) and impaired fasting glycaemia (IFG) in 374 patients with different types of cancer before treatment, by medical records in a Malaga hospital (Spain). We compared the prevalence of basal hyperglycaemia in these patients with general population, within an age range and by gender. RESULTS AND DISCUSSION The prevalence of diabetes was 32.35% in our cancer patients. The comparison depends of age range, and by gender prevalence was: 45-54 years, DM: 40.91% in men cases, versus (vs.) 14.5% in men control (p = 0.005). 55-64 years, IFG: 23.08% in women cases, vs. 5.9% in women control (p = 0.001). 65-74 years, DM: 47.13% in men cases, vs. 25.4% in men control (p = 0.000), and IFG: 23.81% in women cases, vs. 9.5% in women control (p = 0.019). We found a higher prevalence of diabetes in specific types of cancer such as prostate (p < 0.005). Moreover, men had a higher prevalence of diabetes or less diabetes control than women in our cancer sample. CONCLUSIONS We recommend an OGTT (oral glucose tolerance test) for better diagnosis of possible DM in patients with cancer, and an appropriate treatment. It may be an independent risk factor for cancer to have decreased insulin activity, or DM.

Sphenoid sinus metastasis as the presenting manifestation of a prostatic adenocarcinoma: case report and overview of the literature.

Although a metastatic presentation of an occult prostatic adenocarcinoma is not uncommon, the majority of these patients present with bone metastasis affecting the axial skeleton. Cranial metastases to the paranasal sinuses are extremely rare. A 56-year-old man presented with loss of vision and numbness of the right side of the face. Computed tomography (CT) scan and cranial magnetic resonance imaging (MRI) revealed a mass invading the sphenoid sinus. The patient underwent surgery to remove the lesion, and the histopathological examination suggested metastasis of an adenocarcinoma, with positive staining to prostatic specific antigen (PSA). However, serum PSA was 4 ng/mL, and the patient did not report any lower urinary tract symptoms or bone pain. Transrectal ultrasound-guided biopsy revealed prostatic adenocarcinomas with a Gleason score of 8 [4 + 4]. The subsequent treatment consisted of radiotherapy and androgen deprivation, followed by first- and second-line chemotherapy (docetaxel and cabazitaxel) when the disease progressed. The patient achieved a good response with the last cycle of cabazitaxel and after a 5-year followup is currently alive. Cranial metastases of prostate adenocarcinoma are rare, and there is currently no standard treatment for these patients. Whenever possible, surgery combined with radiotherapy and hormonotherapy is the recommended option.

Metastasis of renal cell carcinoma to the buccal mucosa 19 years after radical nephrectomy

Renal cell carcinoma (RCC) has high metastatic potential, which requires early diagnosis to optimize the chance of cure. Metastasis of RCC to the head and neck region is less common and metastasis to the buccal mucosa is extremely rare. This phenomenon occurs mostly in patients with generalized dissemination, especially with lung metastases. In this article we report a case of buccal mucosa metastasis from RCC in a 65-year-old man who presented 19 years after undergoing a left radical nephrectomy for clear cell RCC. Surgical excision of the buccal lesion was performed without evidence of recurrence or new metastatic lesions after 6 years of followup. To our knowledge, this is the first case of metastasis to the buccal mucosa from a RCC reported in the literature.

Primary renal lymphoma: long-term results of two patients treated with a chemotherapy + rituximab protocol.

Primary renal lymphoma (PRL) is a rare disease of which the etiology and pathogenesis remain controversial, and there is currently no standard treatment for it. We present the results of a long-term followup of two patients who were diagnosed with PRL and treated with cyclophosphamide, adriamycin, vincristine, prednisolone and rituximab (CHOP + R) regimen. Both patients reached a complete response, and there is no evidence of recurrence after 4.5- and 5-year followup periods. Based on our experience and other recently published studies, we recommend the combination of CHOP + rituximab as the elective treatment for this disease. To our knowledge, this is the longest followup period with a complete response that has been reported with this modality of treatment.

Nephron-sparing surgery for adenocarcinoma in a renal allograft.

The incidence of malignant tumors in recipients of renal allografts is higher than in the general population. Renal cell carcinoma (RCC) accounts for 4.6% of the tumors in transplanted patients; of them, only 10% are found in transplanted kidneys. Transplantectomy has always been the usual treatment. However, during the last years, nephron-sparing surgery of the allograft is more frequently done in well-selected cases, and therefore dialysis can be avoided. We report the case of a 37-year-old female patient with renal transplant, diagnosed with a 4.5 cm tumor in the lower pole of the renal allograft. The patient underwent partial nephrectomy successfully. Six years after surgery, there is no evidence of recurrence of the disease and the patient maintains an adequate renal function.

Conservative management of unusual keratinising squamous metaplasia of the bladder in a 28-year-old female and overview of the literature.

Keratinizing squamous metaplasia of the bladder is rare and is usually associated with urinary tract infections and chronic irritation. It is considered a precancerous condition of squamous cell carcinoma, especially when more than 50% of the bladder surface is affected. Medical treatment cannot eradicate this lesion. When it is limited to a small area of the bladder, transurethral resection is possible. Annual cystoscopy with multiple biopsies as well as annual upper tract imaging is proposed in the follow up of these patients. We present a preliminary 2-year followup report of a keratinizing squamous metaplasia of the bladder in a 28-year-old female patient with no previous risk factors.

A woman with reddish nodule on the skin of the breast.

A 54-year-old woman presented a peri-areolar nodule located in the skin of the right breast. Clinical examination showed a 6 x 5 cm exophytic, lobed, ulcerated, and bleeding nodule. The patient reported that the tumor had grown gradually over a period of 3 months. The patient had been diagnosed 8 years prior to presentation with infiltrating ductal carcinoma of the right breast (pT2NO). This tumor was treated with partial mastectomy (conservative surgery) and lymph node dissection, then subsequently received 30 tangent field radiotherapy sessions to the breast for a total dose of 45 Gy. The rest of her cutaneous exam was normal. There was no family history of any similar tumor.

Soft tissue extramedullary plasmacytoma.

We present the uncommon case of a subcutaneous fascia-based extramedullary plasmacytoma in the leg, which was confirmed by the pathology report and followed up until its remission. We report the differential diagnosis with other more common soft tissue masses. Imaging findings are nonspecific but are important to determine the tumour extension and to plan the biopsy.

Primary renal lymphoma: report of three new cases and literature review.

OBJECTIVES We report the cases of three patients with primary renal lymphoma. Diagnosis and subsequent treatment are discussed. METHODS The literature on the origin, epidemiology, clinical presentation, diagnosis, treatment and prognosis of primary renal lymphoma was reviewed. RESULTS The first patient was diagnosed after radical nephrectomy and subsequently was given six cycles of CVP (cyclophosphamide, vincristine, prednisone). The diagnosis of the second patient was established by renal biopsy, and the patient received six cycles of CHOP (cyclophosphamide, adriamycin, vincristine and predisone). The last patient had a lymphoma, secondary to immunosuppression, in a transplanted kidney. In this case transplant nephrectomy sufficed to cure the patient's lymphoma. All patients had B-cell non-Hodgkin lymphoma (an extrarenal origin was ruled out by bone marrow biopsy), and were disease-free 15 months, 7 months, and 6.5 years after diagnosis, respectively. CONCLUSIONS Primary renal lymphoma is rare. Diagnosis is established by renal biopsy, although it often presents as a mass simulating renal cell cancer and diagnosis is obtained after radical nephrectomy. Treatment consists of chemotherapy (CHOP). associated with rituximab.

MicroRNA-200 family modulation in distinct breast cancer phenotypes.

The epithelial to mesenchymal transition (EMT) contributes to tumor invasion and metastasis in a variety of cancer types. In human breast cancer, gene expression studies have determined that basal-B/claudin-low and metaplastic cancers exhibit EMT-related characteristics, but the molecular mechanisms underlying this observation are unknown. As the family of miR-200 microRNAs has been shown to regulate EMT in normal tissues and cancer, here we evaluated whether the expression of the miR-200 family (miR-200f) and their epigenetic state correlate with EMT features in human breast carcinomas. We analyzed by qRT-PCR the expression of miR-200f members and various EMT-transcriptional inducers in a series of 70 breast cancers comprising an array of phenotypic subtypes: estrogen receptor positive (ER+), HER2 positive (HER2+), and triple negative (TN), including a subset of metaplastic breast carcinomas (MBCs) with sarcomatous (homologous or heterologous) differentiation. No MBCs with squamous differentiation were included. The DNA methylation status of miR-200f loci in tumor samples were inspected using Sequenom MassArray® MALDI-TOF platform. We also used two non-tumorigenic breast basal cell lines that spontaneously undergo EMT to study the modulation of miR-200f expression during EMT in vitro. We demonstrate that miR-200f is strongly decreased in MBCs compared with other cancer types. TN and HER2+ breast cancers also exhibited lower miR-200f expression than ER+ tumors. Significantly, the decreased miR-200f expression found in MBCs is accompanied by an increase in the expression levels of EMT-transcriptional inducers, and hypermethylation of the miR-200c-141 locus. Similar to tumor samples, we demonstrated that downregulation of miR-200f and hypermethylation of the miR-200c-141 locus, together with upregulation of EMT-transcriptional inducers also occur in an in vitro cellular model of spontaneous EMT. Thus, the expression and methylation status of miR-200f could be used as hypothetical biomarkers to assess the occurrence of EMT in breast cancer.

Non-invasive prenatal diagnosis of multiple endocrine neoplasia type 2A using COLD-PCR combined with HRM genotyping analysis from maternal serum.

The multiple endocrine neoplasia type 2A (MEN2A) is a monogenic disorder characterized by an autosomal dominant pattern of inheritance which is characterized by high risk of medullary thyroid carcinoma in all mutation carriers. Although this disorder is classified as a rare disease, the patients affected have a low life quality and a very expensive and continuous treatment. At present, MEN2A is diagnosed by gene sequencing after birth, thus trying to start an early treatment and by reduction of morbidity and mortality. We first evaluated the presence of MEN2A mutation (C634Y) in serum of 25 patients, previously diagnosed by sequencing in peripheral blood leucocytes, using HRM genotyping analysis. In a second step, we used a COLD-PCR approach followed by HRM genotyping analysis for non-invasive prenatal diagnosis of a pregnant woman carrying a fetus with a C634Y mutation. HRM analysis revealed differences in melting curve shapes that correlated with patients diagnosed for MEN2A by gene sequencing analysis with 100% accuracy. Moreover, the pregnant woman carrying the fetus with the C634Y mutation revealed a melting curve shape in agreement with the positive controls in the COLD-PCR study. The mutation was confirmed by sequencing of the COLD-PCR amplification product. In conclusion, we have established a HRM analysis in serum samples as a new primary diagnosis method suitable for the detection of C634Y mutations in MEN2A patients. Simultaneously, we have applied the increase of sensitivity of COLD-PCR assay approach combined with HRM analysis for the non-invasive prenatal diagnosis of C634Y fetal mutations using pregnant women serum.

Neural crest cell survival is dependent on Rho kinase and is required for development of the mid face in mouse embryos.

Neural crest cells (NCC) give rise to much of the tissue that forms the vertebrate head and face, including cartilage and bone, cranial ganglia and teeth. In this study we show that conditional expression of a dominant-negative (DN) form of Rho kinase (Rock) in mouse NCC results in severe hypoplasia of the frontonasal processes and first pharyngeal arch, ultimately resulting in reduction of the maxilla and nasal bones and severe craniofacial clefting affecting the nose, palate and lip. These defects resemble frontonasal dysplasia in humans. Disruption of the actin cytoskeleton, which leads to abnormalities in cell-matrix attachment, is seen in the RockDN;Wnt1-cre mutant embryos. This leads to elevated cell death, resulting in NCC deficiency and hypoplastic NCC-derived craniofacial structures. Rock is thus essential for survival of NCC that form the craniofacial region. We propose that reduced NCC numbers in the frontonasal processes and first pharyngeal arch, resulting from exacerbated cell death, may be the common mechanism underlying frontonasal dysplasia.
