Safety and tolerability of regorafenib:

xlomafota.13 shared this article with you from Inoreader Safety and tolerability of regorafenib: a real-life experience Via Latest Results for Journal of Gastrointestinal Cancer Abstract Background Regorafenib has been approved among the treatment options for patients with advanced stage colorectal cancer (CRC), hepatocellular carcinoma (HCC), and gastrointestinal stromal tumors (GIST). In this study, we aim to report the real-life experience of the safety and tolerability regorafenib in our institution. Methods We conducted a retrospective chart review of 43 patients who received regorafenib in Kuwait Cancer Control Center (KCCC) from 2016 to the end of 2019. Data collected include diagnosis, patient demographics, performance status, number of previous lines of treatment, number of treatment cycles, side effects, best-tolerated dose, and treatment discontinuation due to intolerability. Univariate analysis with Pearson chi-square test were conducted to study co-relation between discontinuation rates and several factors. Results We had available data for 43 patients (23 males and 20 females). Of the patients, 83.7% had an ECOG performance status of 0 or 1. Seventy-three percent were diagnosed with metastatic CRC, 21% were diagnosed with HCC and 6% were diagnosed with GIST tumors. Half of the patients received 3 lines or more of treatment prior to regorafenib. The median number of cycles received was 3.7 with 11.6% of patients still on active treatment at the time of analysis. The most reported grade 3 and above side effects included rash (41.9%), fatigue (39.6 %), hypertension (25.6%), mucositis (21.9%), hand-foot syndrome (2.3%), and hyperbilirubinemia (4.6%). The best-tolerated dose was 80 mg and that was achieved in 44.2% of patients. The recommended dose of 160 mg could only be achieved in 20.9% of patients. The treatment was discontinued because of intolerability in 25.6% of patients. The discontinuation rates in those with ages 60 years and above versus below 60 years were 91% an d 68%, respectively. Conclusion In our cohort, the best-tolerated dose of regorafenib was 80 mg. Toxicity and intolerability of regorafenib lead to treatment discontinuation in nearly a quarter of patients. Patient age may influence tolerance and adherence to regorafenib. View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.

Gastric Cancer Incidence and Mortality in French Guiana: South American or French?

xlomafota.13 shared this article with you from Inoreader Gastric Cancer Incidence and Mortality in French Guiana: South American or French? Via Latest Results for Journal of Gastrointestinal Cancer Abstract Purpose Gastric cancer is a frequent cancer in the tropics. The objective was to review a decade of gastric cancer data, and to study its spatial and temporal trends. Methods The cancer registry of French Guiana compiled exhaustive data on gastric cancer throughout French Guiana between 2005 and 2014. Age-standardized incidence and mortality rates were computed. Results With 187 new cases recorded, gastric cancer ranked 6th (4.3%). It was more frequent in men than in women. The median age at diagnosis was 62 years for men and 65 years for women. The incidence rate standardized to the world population over the period 2005–2014 was 14.3 cases of gastric cancer per 100,000 man-years and 7.3 per 100,000 woman-years. The death rate from gastric cancer, standardized to the world population over the period 2005–2014, was 8.6 deaths from gastric cancer per 100,000 man-years and 3.4 per 100,000 women-years. These measures were lower than what is reported in Latin America, similar to Martinique and Guadeloupe—two tropical French territories—and higher than in France. Conclusions Gastric cancer affected more males and the median age was younger than in France. Standardized incidence and mortality rates for gastric cancer in French Guiana were between those of France and those of Latin America, and they were comparable to those of the French West Indies. The downward trend in a context of rapid economic growth suggests further gains that could be achieved by improving electricity, water, and sanitation coverage throughout the territory despite challenging geography, and better access to care and Helicobacter pylori eradication.

Endoscopic Ultrasonography is a Promising Tool for Preoperative Prediction of the Operability of Pancreatic Carcinoma

xlomafota.13 shared this article with you from Inoreader Endoscopic Ultrasonography is a Promising Tool for Preoperative Prediction of the Operability of Pancreatic Carcinoma Via Latest Results for Journal of Gastrointestinal Cancer Abstract This work discussed the efficiency of endoscopic ultrasonography (EUS) as a diagnostic modality for early detection of pancreatic cancer. The present study was constructed by doing imaging modalities EUS on 24 patients admitted to surgery department in the faculty of medicine with suspected pancreatic malignancy. Pancreatic cancer was found more in older ages above 55 years predominately in males coming from rural areas presenting with abdominal pain with or without jaundice. Histopathological examination revealed that ductal adenocarcinoma represented by 70.83% of cases. This study also shows significant elevation in serum CA19-9 in the presenting cases to confirm a close relation between cancer pancreas and CA19-9 as a good biochemical marker for PC. EUS was found to be able to detect masses less than 20 mm in diameter. Moreover, EUS can accurately detect the mass nature. EUS showed correct information as regards lymph node involvement and vascular invasion whi ch affected the results of respectability of pancreatic masses. Finally, this study clearly showed that EUS is an accurate pre-operative tool in the assessment of nodal staging, vascular invasion, and respectability in patients with pancreatic adenocarcinoma.

Endoscopic Ultrasound-Guided Ethanol Injection Associated with Trans-arterial Embolization of a Giant Intra-abdominal Cavernous Hemangioma: Case Report and New Therapeutic Option

xlomafota.13 shared this article with you from Inoreader Endoscopic Ultrasound-Guided Ethanol Injection Associated with Trans-arterial Embolization of a Giant Intra-abdominal Cavernous Hemangioma: Case Report and New Therapeutic Option Via Latest Results for Journal of Gastrointestinal Cancer Abstract Background Cavernous hemangiomas are congenital hamartomatous lesions that originate from mesodermal tissue composed of dilated blood vessels. Abdominal pain and palpable mass are the most common presenting symptoms. The different types of treatment for symptomatic patients remain controversial. However, surgical resection is always the most preferred method when possible. To date, there are no reports of endoscopic ultrasound-guided (EUS-guided) absolute ethanol injection as a treatment for such disease when surgery is not an option. Case Presentation A 19-year-old girl with giant cavernous intra-abdominal hemangioma extending to the hepatic hilum, also affecting the gastric wall and occupying the entire supra-mesocolic cavity, initially presents with upper gastrointestinal bleeding and loss of 20 kg in 1 year (BMI = 18 kg/m2). Percutaneous angiography identified a mass with arterial blood supply by the left gastric artery that was embolized. After re-bleeding, an alternative treatment with EUS-guided injection of alcohol was proposed once resection was not feasible without major risks to a young patient. This procedure was repeated 15 and 45 days after the initial treatment, with the ethanol injection of 25 cc and 15 cc, respectively. On the second and third procedure dates, there was evident regression of the hemangioma. On the third procedure, it was possible to identify all anatomic structures that were not clear on the first EUS. After 45 days of last injection, abdominal CT and EUS showed no torious regression of the lesion. Eight months later, abdominal CT showed only a remnant lesion in the hepatogastric ligament with 129 cm3 on volumetry (87% lower in comparison to the initial image), and the patient remains asymptomatic with BMI of 26. In the most recent follow-up CT, 4 years and 2 months after first treatment, the patient presents with a slight increase in the hemangioma—now with 183 cm3 on volumetry. Conclusion Transgastric EUS-guided ethanol injection in the treatment of giant intra-abdominal cavernous hemangioma can provide good outcomes without major complications and can be repeated if necessary.

TERRA Gene Expression in Gastric Cancer: Role of hTERT

xlomafota.13 shared this article with you from Inoreader TERRA Gene Expression in Gastric Cancer: Role of hTERT Via Latest Results for Journal of Gastrointestinal Cancer Abstract Purpose One of the most important serious malignancies is gastric cancer (GC) with a high mortality globally. In this way, beside the environmental factors, genetic parameter has a remarkable effective fluctuation in GC. Correspondingly, telomeres are nucleoprotein structures measuring the length of telomeres and they have special potential in diagnosis of various types of cancers. Defect protection of the telomeric length initiates the instability of the genome during cancer, including gastric cancer. The most common way of maintaining telomere length is the function of the telomerase enzyme that replicates the TTAGGG to the end of the 3′ chromosome. Methods In this review, we want to discuss the alterations of hTERT repression on the modification of TERRA gene expression in conjunction with the importance of telomere and telomerase in GC. Results The telomerase enzyme contains two essential components called telomerase reverse transcriptase (hTERT) and RNA telomerase (hTR, hTERC). Deregulation of hTERT plays a key role in the multistage process of tumorigenicity and anticancer drug resistance. The direct relationship between telomerase activity and hTERT has led to hTERT to be considered a key target for cancer treatment. Recent results show that telomeres are transcribed into telomeric repeat-containing RNA (TERRA) in mammalian cells and are long noncoding RNAs (lncRNAs) identified in different tissues. In addition, most chemotherapy methods have a lot of side effects on normal cells. Conclusion Telomere and telomerase are useful therapeutic goal. According to the main roles of hTERT in tumorigenesis, growth, migration, and cancer invasion, hTERT and regulatory mechanisms that control the expression of hTERT are attractive therapeutic targets for cancer treatment.

Immunohistochemical Expression Pattern of MLH1, MSH2, MSH6, and PMS2 in Tumor Specimen of Iranian Gastric Carcinoma Patients

xlomafota.13 shared this article with you from Inoreader Immunohistochemical Expression Pattern of MLH1, MSH2, MSH6, and PMS2 in Tumor Specimen of Iranian Gastric Carcinoma Patients Via Latest Results for Journal of Gastrointestinal Cancer Abstract Background Gastric cancer is the third leading cause of cancer-related death. Determining molecular and histopathologic tumor features, which may contribute to the development or progression of gastric cancer, can improve the prognosis. Expression patterns of DNA repair proteins such as MLH1, MSH2, MSH6, and PMS2 that are associated with microsatellite instability (MSI) are some of the markers that are useful in predicting the prognosis of gastric cancer. Purpose The purpose was to determine the immunohistochemical expression pattern of MLH1, MSH2, MSH6, and PMS2 in tumor specimens of Iranian gastric carcinoma patients. Methods In this prospective cohort, 186 consecutive patients with gastric cancer, attending Taleghani Hospital, were enrolled. The immunohistochemical expression patterns of MLH1, MSH2, MSH6, and PMS2 in tumor specimens among them were determined. Results The results of this study demonstrated that 91.4% of our gastric cancer patients were negative for MSI, and 8.6% of them were MSI positive. The positive MSI was seen in 5.9% and 15.7% of male and female subjects, respectively, with a significant difference (P = 0.043). The other variables were not related to MSI results (P > 0.05). Conclusion According to the obtained results, the expression of MLH1, MSH2, MSH6, and PMS2 in tumor specimens is positive in 8.6% of the total Iranian gastric cancer sample size, which is mainly positive in female subjects. However, it is not related to the location and stage of the tumor. View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.
