Predictors of Unsuccessful Laparoscopic Resection of Gastric Submucosal Neoplasms

Background

While laparoscopy has become integral to the performance of foregut surgery, its optimal use in resection of gastric submucosal neoplasms, including gastrointestinal stromal tumors (GISTs), remains uncertain. Concern exists for technical feasibility related to tumor size and location, as well as oncologic outcome.

Methods

From 2002 to 2012, 106 patients underwent resection for gastric submucosal neoplasms, comprising 79 laparoscopic and 27 open resections. Median follow-up was 15 months.

Results

Patients were 62?±?14 years and 56 % male. Mean tumor size was 5.5?±?4.3 cm, with 76 % being GISTs. A total of 8 (10 %) conversions occurred in the laparoscopic cohort. On multivariate analysis, conversion was predicted by size greater than 8 cm, while recurrence was predicted by mitotic index (p?<?0.05). Laparoscopic resection resulted in better perioperative outcomes, with less morbidity, operative time, blood loss, and length of stay (p?<?0.05). No significant difference was seen in survival, with 90 % and 81 % alive 3 years after laparoscopic and open resection, respectively (HR 0.4; 95 % CI 0.1–1.3; p?=?0.13).

Conclusions

Laparoscopic resection is feasible and effective in the management of gastric submucosal neoplasms, including GISTs. Caution should be reserved for tumors greater than 8 cm. Oncologic outcome appears to be predicted by tumor biology as opposed to surgical approach.

Genetic unraveling of colorectal cancer

Colorectal cancer is a common disease in both men and women (being the third most common cancer in men and the second most common among women) and thus represents an important and serious public health issue, especially in the western world. Although it is a well-established fact that cancers of the large intestine produce symptoms relatively earlier at a stage that can be easily cured by resection, a large number of people lose their lives to this deadly disease each year. Recent times have seen an important change in the incidence of colorectal cancer in different parts of the world. The etiology of colorectal cancer is multifactorial and is likely to involve the actions of genes at multiple levels along the multistage carcinogenesis process. Exhaustive efforts have been made out in the direction of unraveling the role of various environmental factors, gene mutations, and polymorphisms worldwide (as well as in Kashmir—“a valley of gastrointestinal cancers”) that have got a role to play in the development of this disease so that antitumor drugs could be developed against this cancer, first, and, finally, the responsiveness or resistance to these agents could be understood for combating this global issue.     

Type 2 diabetes mellitus: From a metabolic disorder to an inflammatory condition

Diabetes mellitus is increasing at an alarming rate and has become a global challenge.Insulin resistance intarget tissues and a relative deficiency of insulin secretion from pancreatic β-cells are the major features of type 2 diabetes(T2D).Chronic low-grade inflammation in T2 D has given an impetus to the field of immuno-metabolism linking inflammation to insulin resistance and β-cell dysfunction.Many factors advocate a causal link between metabolic stress and inflammation.Numerous cellular factors trigger inflammatory signalling cascades,and as a result T2 D is at the moment considered an inflammatory disorder triggered by disordered metabolism.Cellular mechanisms like activation of Tolllike receptors,Endoplasmic Reticulum stress,and inflammasome activation are related to the nutrient excess linking pathogenesis and progression of T2 D with inflammation.This paper aims to systematically review the metabolic profile and role of various inflammatory pathways in T2 D by capturing relevant evidence from various sources.The perspectives include suggestions for the development of therapies involving the shift from metabolic stress to homeostasis that would favour insulin sensitivity and survival of pancreatic β-cells in T2 D.     

Interdisciplinary Oncology Education: a National Survey of Trainees and Program Directors in the United States

Oncologists must have a strong understanding of collaborating specialties in order to deliver optimal cancer care. The objective of this study was to quantify current interdisciplinary oncology education among oncology training programs across the USA, identify effective teaching modalities, and assess communication skills training. Web-based surveys were sent to oncology trainees and program directors (PDs) across the USA on April 1, 2013 and October 8, 2013, respectively. Question responses were Yes/No, five-point Likert scales (1 = not at all, 2 = somewhat, 3 = moderately, 4 = quite, 5 = extremely), or free response. Respondents included the following (trainees/PDs): 254/55 medical oncology, 160/42 surgical oncology, 102/24 radiation oncology, and 41/20 hospice and palliative medicine (HPM). Trainees consistently reported lower rates of interdisciplinary education for each specialty compared with PDs as follows: medical oncology 57 vs. 77% (p < 0.01), surgical oncology 30 vs. 44% (p < 0.01), radiation oncology 70 vs. 89% (p < 0.01), geriatric oncology 19 vs. 30% (p < 0.01), and HPM 55 vs. 74% (p < 0.01). The predominant teaching method used (lectures vs. rotations vs. tumor board attendance vs. workshop vs. other) varied according to which discipline was being taught. The usefulness of each teaching method was rated statistically different by trainees for learning about select disciplines. Furthermore, statistically significant differences were found between PDs and trainees for the perceived usefulness of several teaching modalities. This study highlights a deficiency of interdisciplinary education among oncology training programs in the USA. Efforts to increase interdisciplinary education opportunities during training may ultimately translate into improved collaboration and quality of cancer care.
