Differentiated-type VIN is significantly more associated with vulval squamous cell carcinoma than usual-type VIN.

ObjectivesThis study compares clinico-pathological features in young (<40 years) and older patients (>50 years) with colorectal cancer, survival in the young and the influence of pre-operative clinical and histological factors on survival.Materials and methodsA twelve year prospective database of colorectal cancer was analysed. Fifty-three young patients were compared with forty seven consecutive older patients over fifty years old. An analysis of survival was undertaken in young patients using Kaplan Meier graphs, non parametric methods, Cox's Proportional Hazard Ratios and Weibull Hazard models.ResultsYoung patients comprised 13.4 percent of 397 with colorectal cancer. Duration of symptoms and presentation in the young was similar to older patients (median, range; young patients; 6 months, 2 weeks to 2 years, older patients; 4 months, 4 weeks to 3 years, p > 0.05). In both groups, the majority presented without bowel obstruction (young - 81%, older - 94%). Cancer proximal to the splenic flexure was present more in young than in older patients. Synchronous cancers were found exclusively in the young. Mucinous tumours were seen in 16% of young and 4% of older patients (p < 0.05). Ninety four percent of young cancer deaths were within 20 months of operation. At median follow up of 50 months in the young, overall survival was 70% and disease free survival 66%. American Joint Committee on Cancer (AJCC) stage 4 and use of pre-operative chemoradiation in rectal cancer was associated with poor survival in the young.ConclusionIf patients, who are less than 40 years old with colorectal cancer, survive twenty months after operation, the prognosis improves and their survival becomes predictable.

Ureteric injury is rare in obstetric and gynaecological practice but, when it occurs, it has serious implications in terms of both morbidity and litigation. In this review, we evaluate the incidence, aetiology, preventive strategies, diagnosis and management of ureteric injury by systematically reviewing the literature. The incidence of ureteric injury varies between 0.1% and 30%, depending on the type of surgery. Prevention can be attempted by preoperative and intraoperative precautions, although the effectiveness of these measures has not been fully evaluated. Diagnosis of ureteric injury may be made intraoperatively but 70% are diagnosed postoperatively. Management depends on the timing of diagnosis, the aetiology, the length and location of the injury, the extent of the causative operation and the condition of the woman.

Introduction Neuroendocrine carcinoma (NEC) of the cervix is associated with a poor prognosis despite multimodal treatment. The correct diagnosis of this tumor type is imperative to provide clinicians and patients with prognostic information and ensure that appropriate treatment is provided. Methods A clinicopathological study was undertaken on all cervical tumors registered as NEC with the West Midlands Cancer Intelligence Unit between January 1, 1998 and December 31, 2009. Of the 45 cases diagnosed during the study period, the tumor samples of 41 cases were traced, anonymized, and then independently reviewed by 2 gynecological pathologists. Results The review confirmed 31/41 (78%) cases to be NEC, which overall, represented 1.3% of all the cervical cancers registered in the West Midlands over the period of the study. In the correct histological context, synaptophysin was the most sensitive and specific positive immunohistochemical marker of NEC differentiation. The cases that on review were confirmed as NEC had a significantly worse outcome than the non-NEC cases: median survival for NEC cases was 33.3 months versus 315.0 months for the non-NEC cases, P = .013. Conclusions Histological review of a series of NECs has shown significantly reduced survival in those patients with confirmed NEC in comparison with those patients where a diagnosis of NEC was not confirmed. We propose morphological and immunohistochemical criteria for the diagnosis of cervical NEC; and discourage unqualified use of the term "small cell carcinoma" as this does not accurately convey the diagnosis of SCNEC. We urge pathologists to use the 2014 World Health Organization classification when reporting these tumors.
