RESUMO
When peritoneal metastases are diagnosed (strong agreement of experts): (i) seek advice from a multidisciplinary coordination meeting (MCM) with large experience in peritoneal disease (e.g. BIG RENAPE network); (ii) transfer (or not) the patient to a referral center with experience in hyperthermic intraperitoneal chemotherapy (HIPEC), according to the advice of the MCM. With regard to systemic chemotherapy (strong agreement of experts): (i) it should be performed both before and after surgery, (ii) for no longer than 6 months; (iii) without postoperative anti-angiogenetic drugs. With regard to cytoreductive surgery (strong agreement of experts): (i) Radical surgery requires a xiphopubic midline incision; (ii) no cytoreductive surgery via laparoscopy. With regard to HIPEC: HIPEC can be proposed for trials outside an HIPEC referral center (weak agreement between experts): (i) if surgery is radical; (ii) if the expected morbidity is "reasonable"; (iii) if the indication for HIPEC was suggested by a MCM, and; (iv) mitomycin is preferred to oxaliplatin (which cannot be recommended) for this indication.

The peritoneum is a common site of dissemination for colorrectal cancer, with a poorer prognosis than other sites of metastases. In the last two decades, it has been considered as a locoregional disease progression and treated as such with curative intention treatments. Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is the actual reference treatment for these patients as better survival results have been reached as compared to systemic chemotherapy alone, but its therapeutic efficacy is still under debate. Actual guidelines recommend that the management of colorectal cancer with peritoneal metastases should be led by a multidisciplinary team carried out in experienced centers and consider CRS + HIPEC for selected patients. Accumulative evidence in the last three years suggests that this is a curative treatment that may improve patients disease-free survival, decrease the risk of recurrence, and does not increase the risk of treatment-related mortality. In this review we aim to gather the latest results from referral centers and opinions from experts about the effectiveness and feasibility of CRS + HIPEC for treating peritoneal disease from colorectal malignancies.

One of the current international prospective clinical trials of the EORTC Melanoma Cooperative Group explores the usage of regional isolated perfusion as adjuvant in melanomas located on the extremities. In the design of the study it is necessary to define not only the extent of the surgery (perfusion+local excision versus local excision only), but also to ensure uniformity of surgery performed between surgeons and institutions. With on-site visits and general meetings with the participants, surgical protocol violations and misinterpretations of the protocol could be avoided. The conclusion is that accurate surgical quality control is time consuming, but not difficult.

This study evaluated conservative joint-sparing surgery for patients with osteosarcoma around the knee. Of 23 patients with stage IIB osteosarcoma around the knee, 5 were treated with long-term (30-56 weeks) local intensive preoperative chemotherapy consisting of high-dose methotrexate, intra-arterial and intravenous cisplatinum, doxorubicin, and hyperthermic isolated regional perfusion. More conservative resection, sparing the knee joint, was performed with smaller sufficient surgical margin in these 5 patients, preserving good limb function. Excellent local effects were achieved in the resected specimens. These results suggest long-term local intensive preoperative chemotherapy, including intra-arterial cisplatin and hyperthermic isolated regional perfusion, help control local tumor and allow for more conservative surgery.

Although cutaneous melanoma is rare in African-Americans, it continues to have a poor prognosis. We reviewed our experience with 13 African-American patients who had cutaneous melanoma diagnosed between 1969 and 1990. Eight of these 13 lesions were on the foot. These lesions were seen at a late stage, and 50% of them were more than 3 mm in thickness. Nine of these 13 patients had recurrent disease. This series of patients had a 92% 1-year and a 61% actuarial 5-year survival, with a median follow-up of 45 months. This study emphasizes the need for awareness of the occurrence of this disease in the African-American population in an effort to reduce the mortality from cutaneous melanoma.
