Prognosis of elderly gastric cancer patients after surgery: a nomogram to predict survival.

This study aimed to identify clinicopathological factors associated with the outcome of elderly patients with gastric cancer (GC), and to construct a nomogram for individual risk prediction. Tumor characteristics of 143 patients aged ≥ 80 years underwent surgery for GC were collected and analyzed by uni- and multivariate analyses. A prognostic nomogram was constructed using the factors which resulted to be significantly associated with overall survival. Discrimination of nomogram was tested by Kaplan-Meier (KM) curves and boxplots. With a median follow up of 18.37 months, overall 1-year survival rate was 51% and it was 60 and 40% for older and younger than 83 years, respectively (P = 0.003). Univariate analysis indicated that age (P = 0.008), pre-operatory performance status (P < 0.001), depth of invasion (P = 0.007), lymph nodes involvement (P < 0.001), and residual tumor (P < 0.001) were significant prognostic factors. Based on these variables, a nomogram to predict 3, 6, 12, and 24 months survival probability after GC surgery was developed. KM and boxplots according to the range of nomogram total points highlighted the appropriateness of distinguish the patients' survival in all the subgroups. Moreover, this nomogram exhibited superior prognostic discrimination between intermediate stages (II-III) than AJCC-TNM classification. This study showed that after good surgical selection, the prognosis of elderly GC patients may be influenced by several clinicopathological factors. Therefore, a predictive nomogram to distinguish more accurately fit patients may allow physicians to individualize treatments and to detect those patients who may benefit from an intensive multidisciplinary approach.

Gunshot wound without entrance hole: where is the trick? - a case report and review of the literaturer.

The presence at CT scan of more retained bullets than expected could be a very difficult interpretation challenge in the early management of gunshot wounds. The modern non operative management of haemodinamically stable patients without peritonitis requires that the trajectory of the bullet is clearly recognized. This clinical case reporting of a gunshot wound without evident entry hole, allows to discuss the diagnostic and therapeutic implications in the management of gunshot wounds cases with atypical entry and/or exit holes.

Parietal and peritoneal localizations of hepatocellular carcinoma: is there a place for a curative surgery?

BACKGROUND: The clinical course of peritoneal and parietal recurrence of hepatocellular carcinoma (HCC-PPL) is not well known. METHODS: Twenty-eight patients with a histologically proven HCC-PPL were analyzed out of a series of 515 patients operated for HCC (group 1). The risk factors, histological features, growing dynamic and results of surgical treatment were analyzed and compared with patients having other extrahepatic localizations of HCC (group 2; 26 patients). Survival data were also compared with patients with intrahepatic-only recurrence (group 3; 211 patients). RESULTS: In group 1, a needle tract injury was present in 57.1% and a previous spontaneous rupture in 14.3% of cases. Parietal seeding was generally single, while peritoneal seeding was frequently multiple. Grading was poor in 84.7%, microvascular infiltration was observed in 57.1% and a rapid growth in 55.5% of cases. In Group 2, only 4 out of 26 patients underwent surgery. Survival was significantly better in group 3 than in group 1, and in group 1 than in group 2. CONCLUSIONS: Extrahepatic HCC recurrence is related to an aggressive biology of the cancer; many characteristics of high malignancy are usually present in these cases. After radical surgery for HCC-PPL, an acceptable survival may be obtained.
