Hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) is associated with a dismal prognosis. Atezolizumab plus bevacizumab (atezo-bev) is the recommended palliative treatment, and approximately 10% of the patients may experience a complete response (CR), according to the mRECIST criteria. The treatment duration is until disease progression or unacceptable side effects occur. Long-term continuation can cause potential toxicities and a substantial financial burden, making early treatment discontinuation a viable option. This report describes durable CR after discontinuing atezo-bev treatment in three patients with HCC and PVTT.

Purpose: The bisecting angle technique (BAT) encounters difficulties in positioning the X-ray cone and aligningthe central beam with the tooth. To address this, a rectangular laser featuring a pointed light was integrated into theintraoral X-ray cone. This study evaluated its effectiveness in improving radiograph quality and minimizing errors. Materials and Methods: Fifty fifth-year Bachelor of Dental Surgery students were divided into 3 groups. Group1 (n = 16) used the paralleling technique, group 2 (n = 17) employed the conventional BAT, and group 3 (n = 17) utilized the laser-assisted BAT on mannequins. Two independent oral radiologists assessed the quality of the radiographs, categorizing the images as either diagnostically acceptable or not acceptable. Inter-group comparisons of quality and error rates were conducted using the chi-square test (significance level: P<0.05). Results: The paralleling technique group produced 77.5% diagnostically acceptable radiographs and 22.5% that were not diagnostically acceptable. These percentages were 65.3% and 34.7%, respectively, in the conventional BAT group and 75.3% and 24.7%, respectively, in the laser-assisted BAT group, showing results similar to the paralleling technique group. The quality of radiographs differed significantly among the groups (P<0.05). The percentage of error-free radiographs was 38.1% in the paralleling technique group, 20.6% in the conventional BAT group, and 40.0% in the laser-assisted BAT group, with these differences being statistically significant (P<0.05). Conclusion The device produced higher acceptability and fewer radiographic errors than the conventional BATtechnique, suggesting accurate adjustment of the X-ray cone and central beam to the desired teeth.

Background: Oral cavity cancers, the second most common type in India, are responsible for 10% of the overall cancer burden. With a recurrence rate of 30% to 40% and a 5-year survival rate of 50%, these malignancies account for substantial morbidity and mortality. Despite advances in treatment modalities, survival rates following treatment completion have not improved significantly. The present study aimed to establish specific epidemiological and pathological factors responsible for recurrence after treatment completion in buccal mucosa cancers. Methods: A retrospective analysis of the data of 116 patients treated for biopsy-proven cancers of the buccal mucosa was undertaken 1 year after treatment completion. Factors such as age, sex, education, lymphovascular invasion, extranodal extension (ENE), perineural invasion, depth of invasion, and pathological margin status were compared between patients who presented with recurrence and those who did not. Statistical significance was set at p< 0.05. Results: Of the 116 patients, 40 (34.5%) developed a recurrent disease within 1 year. The mean age of the study population was 43.3 years, and males constituted 91.4% of the included patients. Ipsilateral buccal mucosa was the commonest site of disease recurrence. Neck node metastasis, ENE, and margins of resection < 5 mm were significantly related to the recurrence of disease. However, surprisingly, lymphovascular invasion, perineural invasion, and depth of invasion > 10 mm did not show statistically significant associations. Conclusion Neck node metastasis, ENE, and margins of resection < 5 mm were the histopathological factors associated with recurrence in cancers of the buccal mucosa.

Approximately 20% of hepatocellular carcinomas (HCC) occur in noncirrhotic livers. Resection may be considered for patients with HCC, provided sufficient future liver remnant is available, regardless of the tumor size. Tumors located posteriorly near the right hepatic vein (RHV), or inferior vena cava can be managed through anterior or caudal approaches. RHV is typically conserved during right posterior sectionectomy. When a large posteriorly placed tumor causes chronic compression on RHV, the right anterior section drainage is redirected preferentially to the middle hepatic vein. The division of RHV in such instances does not cause congestion of segments 8 and 5. The technical complexity of laparoscopic right posterior sectionectomy arises from the large transection surface, positioned horizontally. We describe in this multimedia article, a case of large HCC in segments 6 and 7, which was successfully treated using laparoscopic anatomic right posterior sectionectomy.
