We investigated factors affecting 5-year survival in patients undergoing hepatic resection for colorectal cancer metastases, including events long after initial hepatectomy. Although retrospective studies have demonstrated survival benefit of hepatectomy for metastatic colorectal cancer, few have included sufficient 5-year survivors to identify survival-related factors throughout the clinical course. ⋯ Reoperations for each recurrence of metastases, followed by additional chemotherapy, frequently resulted in long survival.

The number of aged patients with head and neck cancer is increasing. Comorbidities are common in this population. It is necessary to evaluate the effect of comorbidities as measured with the ACE-27 index on recurrence and survival of elderly patients with head and neck cancer, adjusting by other prognostic factors as age, clinical stage and functional status index. ⋯ Comorbidity measured with ACE-27 was a prognostic factor for overall survival in patients older than 70 years with head and neck cancer. The Karnofsky performance index could be included in multivariable analysis of survival for older patients with head and neck cancer.

Positive/close margins are associated with higher in-breast failure rates after breast-conserving surgery (BCS). We investigated whether intraoperative margin assessment aids in obtaining negative margins, and to evaluate the local control thus achieved. ⋯ Intraoperative assessment of margins assisted in identifying positive/close margins and allowed over a quarter of the patients to be rendered margin-negative with intraoperative re-excision at their original operation. This approach resulted in excellent local control in patients treated with BCS and radiation.

This is a phase II study, the aim of which is to determine if a laparoscopic approach can be used in pelvic autonomic nerve-preserving surgery for patients with lower rectal cancer following chemoradiation therapy. ⋯ By the laparoscopic approach, total preservation of pelvic autonomic nerves without compromise of the radical extirpation of tumor is technically feasible in the vast majority of patients with lower rectal cancer who have undergone concurrent chemoradiation therapy, thus facilitating the retention of genitourinary function in a significant proportion of such patients.

The aim of this study was to test a new strategy for radioguided management of malignant or suspicious nonpalpable breast lesions, with a combination of radioguided occult lesion localization (ROLL), sentinel lymph node (SLN) mapping, and, if necessary, immediate local surgery and SLN biopsy with a single injection of (99m)Tc-labeled dextran for the whole procedure. ⋯ ROLL and SLN biopsy are emerging procedures that can be used simultaneously. They permit exact breast lesion excision, immediate local breast surgery, and intraoperative SLN biopsy in a single procedure. The combination of radioguided nonpalpable lesion localization and SLN biopsy is a suitable alternative to working up subclinical imaging-detected breast carcinomas.
