The efficacy of physiotherapy upon shoulder function following axillary dissection in breast cancer, a randomized controlled study.

BackgroundMany patients suffer from severe shoulder complaints after breast cancer surgery and axillary lymph node dissection. Physiotherapy has been clinically observed to improve treatment of these patients. However, it is not a standard treatment regime. The purpose of this study is to investigate the efficacy of physiotherapy treatment of shoulder function, pain and quality of life in patients who have undergone breast cancer surgery and axillary lymph node dissection.MethodsThirty patients following breast cancer surgery and axillary lymph node dissection were included in a randomised controlled study. Assessments were made at baseline and after three and six months. The treatment group received standardised physiotherapy treatment of advice and exercises for the arm and shoulder for three months; the control group received a leaflet containing advice and exercises. If necessary soft tissue massage to the surgical scar was applied. Primary outcome variables were amount of pain in the shoulder/arm recorded on the Visual Analogue Scale, and shoulder mobility (flexion, abduction) measured using a digital inclinometer under standardized conditions.Secondary outcome measures were shoulder disabilities during daily activities, edema, grip strength of both hands and quality of life. The researcher was blinded to treatment allocation.ResultsAll thirty patients completed the trial. After three and six months the treatment group showed a significant improvement in shoulder mobility and had significantly less pain than the control group. Quality of life improved significantly, however, handgrip strength and arm volume did not alter significantly.ConclusionPhysiotherapy reduces pain and improves shoulder function and quality of life following axillary dissection after breast cancer.Trial registrationISRCTN31186536

Comparison between local ablative therapy and chemotherapy for non-resectable colorectal liver metastases: a prospective study.

BackgroundThere is a growing interest for the use of local ablative techniques in patients with non-resectable colorectal liver metastases. Evidence on the efficacy over systemic chemotherapy is, however, extremely weak. In this prospective study we aim to assess the additional benefits of local tumour ablation.MethodsA consecutive series of 201 colorectal cancer patients, without extrahepatic disease, that underwent laparotomy for surgical treatment of liver metastases, were prospectively followed for survival and HRQoL. At laparotomy three groups were identified: patients in whom radical resection of metastases proved feasible, patients in whom resection was not feasible and received local ablative therapy, and patients in whom resection or local ablation was not feasible for technical reasons and who received systemic chemotherapy.FindingsPatients in the chemotherapy and in local ablation group were comparable for all prognostic variables tested. For the local ablation group overall survival at 2 and 5 years was 56 and 27%, respectively (median 31 months, nxa0=xa045), for the chemotherapy group 51 and 15%, respectively (median 26xa0months, nxa0=xa039) (Pxa0=xa00.252). After resection these figures were 83 and 51%, respectively (median 61xa0months, nxa0=xa0117) (Pxa0<xa00.001). The median DFS after local ablation was 9xa0months, HRQoL was restored within 3xa0months. Patients after local ablation gained far more QALY’s (317) than in the chemotherapy group (165) (Pxa0<xa00.001).InterpretationAlthough overall survival did not reached statistical significance, the median DFS of 9xa0months suggests a beneficial effect of local tumour ablation for non-resectable colorectal liver metastases. Moreover, compared with systemic chemotherapy more QALY’s were gained after local ablative therapy.

The management of clear cell sarcoma.

Clear cell sarcoma is a rare soft tissue tumour, constituting approximately 1% of all soft tissue sarcomas. Prognosis is reported to be poor due to the great propensity to metastasise regionally and distantly. In this paper, we report the surgical experience of two university hospitals. Both disease-free and overall survival after resection of clear cell sarcoma in this limited study were excellent, which may be explained by relatively small tumour size in seven out of eight patients and adjuvant radiation treatment. The current treatment for clear cell sarcoma is wide local tumour excision, with adjuvant radiation therapy for resection margins of less than 1 mm.

Metalloproteinases and Their Regulators in Colorectal Cancer

Metalloproteinases (MPs) such as the matrix metalloproteinases (MMPs) and adamalysins (ADAMs and ADAMTS) are expressed in various stages of colorectal cancer (CRC), and some correlate with survival and prognosis. The MPs are regulated by various factors including EMMPRIN, TIMPs, and RECK. In addition, micro‐RNAs are found to be relevant for both MP expression levels and CRC prognostication. Both MPs and their regulators could be potential targets for intervention and therapy in CRC. J. Surg. Oncol. 2010; 101:259–269.

Magnetic resonance imaging in size assessment of invasive breast carcinoma with an extensive intraductal component

BackgroundBreast-conserving treatment of invasive breast carcinoma with an extensive intraductal component (EIC) is associated with DCIS-involved surgical margins and therefore it has an increased recurrence rate. EIC is a non-palpable lesion of which the size is frequently underestimated on mammography. This study was undertaken to evaluate the accuracy of MRI in size assessment of breast cancer with EIC.Methods23 patients were identified and the mammographic (n = 21) and MR (n = 23) images were re-reviewed by a senior radiologist. Size on MR images was compared with histopathological tumour extent.ResultsThe correlation of radiological size with histopathological size was r = 0.20 in mammography (p = 0.39) compared to r = 0.65 in MRI (p < 0.01). Mammography underestimated histopathological tumour size in 62%. MR images over- or underestimated tumour size in 22% and 30% of the cases, respectively. In poorly differentiated EIC, MRI adequately estimated the extent more often compared to moderately differentiated EIC (60% versus 25%, respectively).ConclusionSize assessment of MRI imaging was more accurate compared to mammography. This was predominantly true for poorly differentiated EIC.

Level of Fluorodeoxyglucose Uptake Predicts Risk for Recurrence in Melanoma Patients Presenting With Lymph Node Metastases

BackgroundThe incidence of malignant melanoma has increased. Identification of additional prognostic factors may allow the development of individualized strategies. This multivariate analysis was undertaken to evaluate the potential role of the standard uptake value (SUV) in predicting disease-free and overall survival in melanoma patients with lymph node metastases.MethodsAll melanoma patients with palpable lymph node metastases who where referred for a fluorodeoxyglucose positron emission tomography scan were eligible. The SUV in the lymph node metastasis was calculated. Data were analyzed (Kaplan-Meier), and differences in cumulative survival and the disease-free rate were assessed (log-rank test). Univariate and multivariate analyses (Cox proportional hazard model) were performed to determine independent prognostic factors.ResultsThere was no statistical difference in survival for the 38 patients with a high or low SUVmean (P = .11). However, a significant difference was found in disease-free survival (P = .03). Ulceration of the primary melanoma (P = .023) was an independent predictor of survival. For the disease-free survival, multivariate Cox regression showed adjuvant radiation (P = .001), localization of the primary melanoma (P = .017), and a high SUVmean (P = .009) as independent prognostic factors.ConclusionsDisease-free survival of melanoma patients was prolonged in those with a low SUVmean value (P = .03) in their lymph node metastasis, as compared with those with a high SUVmean. However, this difference was not found for overall survival. In multivariate analysis, high SUVmean was an independent prognostic factor (P = .009) for disease-free survival. Prospective research should determine whether patients with a high FDG uptake in melanoma lymph node metastases could benefit from adjuvant radiation treatment or chemotherapy.The incidence of malignant melanoma has increased.

MALIGNANT TESTICULAR GERM-CELL TUMORS IN FATHER AND SON - A REPORT ON 2 FAMILIES

Abstract Familial occurrence of malignant testicular tumors is rare. Of 374 patients we found 2 families in which father and son had a testicular tumor. In the first family the father had a teratocarcinoma, while the son was treated initially for seminoma and later for embryonal carcinoma. In the second family the father had a seminoma and the son had an embryonal carcinoma.
