Low-power laser therapy for gastrointestinal neoplasia

The Role of Surgery in the Management of Gastric Cancer: State of the Art

Surgery still represents the mainstay of treatment of all stages of gastric cancer (GC). Surgical resections represent potentially curative options in the case of early GC with a low risk of node metastasis. Sentinel lymph node biopsy and indocyanine green fluorescence are novel techniques which may improve the employment of stomach-sparing procedures, ameliorating quality of life without compromising oncological radicality. Nonetheless, the diffusion of these techniques is limited in Western countries. Conversely, radical gastrectomy with extensive lymphadenectomy and multimodal treatment represents a valid option in the case of advanced GC. Differences between Eastern and Western recommendations still exist, and the optimal multimodal strategy is still a matter of investigation. Recent chemotherapy protocols have made surgery available for patients with oligometastatic disease. In this context, intraperitoneal administration of chemotherapy via HIPEC or PIPAC has emerged as an alternative weapon for patients with peritoneal carcinomatosis. In conclusion, the surgical management of GC is still evolving together with the multimodal strategy. It is mandatory for surgeons to be conscious of the current evolution of the surgical management of GC in the era of multidisciplinary and tailored medicine.

Cost-effectiveness of palliative surgery versus nonsurgical procedures in gastrointestinal cancer patients

Palliative care is an essential component to multidisciplinary cancer care. Improved symptom control, quality of life (QOL), and survival have resulted from its utilization. Cost-effectiveness and utility analyses are significant variables that should be considered in comparing benefits and costs of medical interventions to determine if certain treatments are economically justified. This is a review on the cost-effectiveness of palliative surgery compared to other nonsurgical palliative procedures in patients with unresectable gastrointestinal cancers. J. Surg.

Determination of Effective Factors on Survival of GI Cancers: Results of Five Years Follow up in Iranian Population

Background:

The gastrointestinal cancers are among the most common cause of cancer-related death and their long term survival is very low. This study was aimed to determine the effective factors on survival of gastrointestinal cancers among Iranian population during 5 years of follow up.

Methods:

In total, 157 patients diagnosed as gastrointestinal cancers from 2007 to 2009 in the only center of endoscopy in Alvand city, northwest of Qazvin province were included and followed for five years. The univariate and multivariate analysis were done using Kaplan-Meier method and the Cox model respectively.

Results:

Observations of 146 patients were analyzed (99 (67.8%) males and 47 (32.2%) females). The mean age was 64.73± 13.23 and 58.28±13.91 for females and males respectively. The one and three years survival rates for esophageal cancer were 28% and 9% and the one, three and five years survival rates for gastric cancer were 31%, 26% and 14% and for colorectal cancer were 96%, 86% and 75% respectively. In the univariate analysis, variables of age, educational level, ethnicity, smoking, type of cancer, stage of disease and type of treatment had significant effects on survival. In the multivariate analysis, the type of cancer and type of treatment affected the survival of patients as effective factors (p<005).

Conclusion:

Patients with esophageal cancer and those who underwent RT &/or CT are exposed to higher risk of death. Combination therapies (Surgery and adjuvant or neoadjuvant therapy) were related to be her survival. Early diagnosis and use of extended cancer screening programs seem necessary to improve survival.

Is there a role for nontraditional resection of early gastric cancer?

Current trends in the treatment of gastric cancer indicate the emergence of a more sophisticated approach, with tailored therapy applied to individual cases. Treatment includes a broader spectrum of therapeutic options (Fig. 3), including EMR, laparoscopic or laparoscopy-assisted surgery, modified radical surgery, and typical radical surgery with lymph node dissections. Precise characterization of the lesions, especially the depth of invasion in the gastric wall, its size, histology and whether there is ulceration, is the key to successful treatment of N0 mucosal cancer. Micrometastasis and metastasis at the molecular level are issues that require further investigation. Laparoscopic surgery may be more widely accepted. The limitations of nodal dissection based on the concept of a sentinel node should be carefully evaluated in future studies. [figure: see text] Many treatment options, ranging from minimally invasive surgery to D2 node dissection, are available to the surgical oncologist who is treating EGC. As more information is gathered, surgeons will be better able to select patients who are good candidates for minimal surgical procedures.
