RESUMEN
Pancreatic cancer remains an aggressive disease with a 5 year survival rate of 5%. Only 15% of patients with pancreatic cancer are eligible for radical surgery. Evidence suggests a benefit on survival with adjuvant chemotherapy (gemcitabine o fluourouracil) after R1/R0 resection. Adjuvant chemoradiotherapy is also a valid option in patients with positive margins. Borderline resectable pancreatic cancer is defined as the involvement of the mesenteric vasculature with a limited extension. These tumors are technically resectable, but with a high risk of positive margins. Neoadjuvant treatment represents the best option for achieving an R0 resection. In advanced disease, two new chemotherapy treatment schemes (Folfirinox or Gemcitabine plus nab-paclitaxel) have showed improvements in overall survival compared with gemcitabine alone. Progress in pancreatic cancer treatment will require a better knowledge of the molecular biology of this disease, focusing on personalized cancer therapies in the near future.

PURPOSE: Preoperative chemoradiotherapy and local excision via transanal endoscopic surgery (TEM) in T2-3s,N0,M0 rectal cancer achieve promising results in selected patients. We describe our long-term follow-up experience with this combination, and evaluate complete clinical and pathological responses, local recurrence and overall survival. METHODS: The prospective observational follow-up study carried out since 2007. Out of 476 consecutive patients treated with TEM, we selected those with adenocarcinoma of low or moderate grade of differentiation, clinical stages T2-superficial T3,N0,M0, who refused radical surgery. Preoperative chemoradiotherapy comprised 5-fluorouracil or capecitabine combined with radiotherapy at a dose of 50.4 Gy. TEM was performed after 8 weeks. Complications were recorded and long-term follow-up was conducted. RESULTS: Fifteen patients undergoing preoperative chemoradiotherapy and TEM (median age 76 years, 95 % CI 70.3-80.4, and median follow-up 38 months, 95 % CI 20-44) were studied. No local recurrence was observed, and only one patient (6.7 %) presented systemic relapse. The overall survival was 76 %. Complete clinical response was achieved in seven patients (46.7 %) and complete pathological response in four (26.7 %). With regard to toxicity associated with neoadjuvant treatment, four patients (26.7 %) developed grade 3 adverse effects; no grade 4 or 5 adverse effects were observed. There was no postoperative mortality. CONCLUSIONS: The results of our study, with a response rate of 26.7 % and without local relapse, support the treatment of T2-3s,N0,M0 of rectal cancer with preoperative chemoradiotherapy and local excision (TEM).

Oxaliplatin has been classified as an irritant drug. Less than 10 cases of oxaliplatin extravasation through a central venous access have been described to date. We present a case of extravasation through a central venous access, of the highest dose (165 mg) of oxaliplatin reported to date. We confirmed the irritant effect, and full recovery from toxicity was achieved. We describe the treatment administered and offer a review of literature.

OBJECTIVE: To provide an outpatient facility to improve the management of chemotherapy toxicity in cancer patients. PATIENTS AND METHODS: We set up an oncology acute toxicity unit (OATU) to improve toxicity management. A telephone helpline was the initial contact which filters out inappropriate non-toxicity-related events. Patients were provided an information booklet describing the possible side effects of the chemotherapy and the helpline telephone number. A specialist nurse received the calls and consulted the doctor if necessary. Depending on requirements, the patient's problem was resolved by telephone, or a consultation visit at the OATU was arranged. RESULTS: Between February 1999 and August 2001, 1126 patients made 2007 contacts with the OATU. The most common tumours were breast (26%), colorectal (20%) and lung (20%). The telephone helpline was used in 87% of contacts and 37% were considered inappropriate. Of the 1263 appropriate contacts, the most frequent chemotherapy schedules that had been administered were 5FU-leucovorin (11.2%) and CMF (10.4%). The most frequent side effects were fever (35.5%), diarrhoea (18.5%), mucositis (16.2%) and emesis (13%). The problem was resolved by telephone in 48% of cases and 52% required attendance in the OATU, of which 40% required hospital admission, i.e., 21.1% of the initial appropriate helpline contacts. The most frequent reason was Grade 3-4 neutropenic fever (56.5%). CONCLUSIONS: The OATU enables prompt and efficient access of patients to medical oncology facilities in the event of toxicity due to chemotherapy. Unnecessary emergency room use is avoided while oncology outpatient and hospitalisation facilities are optimised.
