Multicenter Study
Does solar exposure, as indicated by the non-melanoma skin cancers, protect from solid cancers: vitamin D as a possible explanation.
Skin cancers are known to be associated with sun exposure, whereas sunlight through the production of vitamin D may protect against some cancers. The aim of this study was to assess whether patients with skin cancer have an altered risk of developing other cancers. ⋯ Vitamin D production in the skin seems to decrease the risk of several solid cancers (especially stomach, colorectal, liver and gallbladder, pancreas, lung, female breast, prostate, bladder and kidney cancers). The apparently protective effect of sun exposure against second primary cancer is more pronounced after non-melanoma skin cancers than melanoma, which is consistent with earlier reports that non-melanoma skin cancers reflect cumulative sun exposure, whereas melanoma is more related to sunburn.

We aimed to assess the ability of (18)F-fluorodeoxyglucose (FDG)-positron emission tomography (PET) scan to predict pathologic complete response (CR) and survival in patients with oesophageal cancer treated with preoperative chemoradiotherapy (CRT). The study cohort consisted of 62 consecutive patients with operable oesophageal cancer who were treated with preoperative CRT followed by oesophagectomy. Endoscopy, computed tomography (CT) and PET were performed before and after CRT. ⋯ The variables associated with pre-CRT PET scan were not predictive of survival. In conclusion, CMR by FDG-PET has a significant correlation with pathologic CR and can predict the long-term outcome in oesophageal cancer patients undergoing CRT. Although surgery is standard treatment for respectable oesophageal cancer, currently even in patients with CMR, the addition of (18)F-FDG-PET could be used to select the patient subgroup not requiring surgery.

Anthracycline-induced cardiotoxicity after treatment for childhood cancer is a considerable and serious problem. In this review, important insight into the current state of the evidence on the use of different cardioprotective agents, different anthracycline analogues, and different anthracycline infusion durations to reduce or prevent cardiotoxicity in children treated with anthracyclines is provided. It has become clear that, at the present time, there is not enough reliable evidence for many aspects of the prevention of anthracycline-induced cardiotoxicity in children. ⋯ With regard to the use of the cardioprotectant dexrazoxane, it might be justified to use dexrazoxane in children if the risk of cardiac damage is expected to be high. However, for each individual patient, care providers should weigh the cardioprotective effect of dexrazoxane against the possible risk of adverse effects including a lower response rate. We recommend its use in the context of well-designed studies.

Randomized Controlled Trial Multicenter Study
Randomised trial of drains versus no drains following radical hysterectomy and pelvic lymph node dissection: a European Organisation for Research and Treatment of Cancer-Gynaecological Cancer Group (EORTC-GCG) study in 234 patients.
Drainage, following radical hysterectomy and pelvic lymph node dissection to prevent postoperative lymphocyst formation and surgical morbidity, is controversial. To study the clinical significance of drainage, 253 patients were registered and 234 patients were randomised into two arms. In one arm (n=117) postoperative drainage was performed, in the other arm (n=117) no drains were inserted. ⋯ The difference showed a p-value of 0.06 in Fisher's Exact test. The operating time was related to the occurrence of postoperative lymphocyst formation. It was concluded that drains can be safely omitted following radical hysterectomy and pelvic node dissection without pelvic reperitonisation in patients without excessive bleeding during or oozing at the end of surgery.

Multicenter Study
Exatecan in pretreated adult patients with advanced soft tissue sarcoma: results of a phase II--study of the EORTC Soft Tissue and Bone Sarcoma Group.
No standard treatment is established for patients with advanced soft tissue sarcoma after previous chemotherapy with anthracyclines and ifosfamide, given either in combination or sequentially. Exatecan (DX-8951f) is a totally synthetic analogue of the topoisomerase I-inhibitor camptothecin, which was synthesised to impart increased aqueous solubility, greater tumour efficacy, and less toxicity than camptothecin itself, topotecan or irinotecan. Since some activity against soft tissue sarcomas, especially leiomyosarcomas, has been reported for topoisomerase I-inhibitors, a study with a new and more potent agent seemed justified. ⋯ Using a two-step statistical design, the trial was stopped after the first step in both strata, due to lack of activity. In pretreated soft tissue sarcoma patients, Exatecan is well tolerated but does not achieve any objective responses. However, with respect to progression-free survival, Exatecan did show some activity in leiomyosarcomas.
