Article Synopsis
  • A study was conducted to compare robotic minor liver resections (RMLR) with laparoscopic minor liver resections (LMLR) in patients undergoing surgery on the anterolateral liver segments.
  • The analysis included over 10,000 patients and employed propensity score matching to balance the groups for accuracy in comparisons.
  • Results indicated RMLR had benefits like less blood loss, lower major morbidity, and shorter hospital stays than LMLR, although the difference in 30-day readmission rates suggested RMLR may have some drawbacks.

Postoperative infectious complications are extremely important to surgeons and the entire medical care team. Among these complications, surgical site infection (SSI) appears to be one of the earliest and most prevalent events and is considered an inherent complication of surgical procedures. In oncological patients submitted to resections of digestive system tumors, there is a confluence of several risk factors for SSI, making it necessary to establish measures to maximize the control of this condition to provide a better prognosis for these patients.

Article Synopsis
  • The CABASTY study investigated the effects of biweekly administration of a lower dose of cabazitaxel on pain and quality of life for older men with metastatic castration-resistant prostate cancer (mCRPC).
  • In a trial involving 196 patients, researchers compared biweekly dosing (16 mg/m) to a standard triweekly dosing (25 mg/m) regarding pain progression and health-related quality of life (HRQoL).
  • Results showed no significant differences in pain progression or HRQoL between treatment groups, but the biweekly group experienced a delayed onset of some adverse events, suggesting it could be a safer option for older patients.

Article Synopsis
  • Minimally invasive liver resections (MILR) can reduce blood loss and recovery time compared to traditional methods, but the impact of cirrhosis on these procedures is not fully understood.
  • A study reviewed data from 2534 patients who underwent minimally invasive major liver surgeries worldwide, focusing on outcomes related to different levels of cirrhosis.
  • Results showed that advanced cirrhosis leads to higher blood transfusion rates, more postoperative complications, and longer hospital stays, suggesting that cirrhosis severity should be considered in future assessments of surgical difficulty in MILR.*

Importance: Many patients 65 years or older with metastatic castration-resistant prostate cancer (mCRPC) are denied taxane chemotherapy because this treatment is considered unsuitable.

Objective: To determine whether biweekly cabazitaxel (CBZ), 16 mg/m2 (biweekly CBZ16), plus prophylactic granulocyte colony-stimulating factor (G-CSF) at each cycle reduces the risk of grade 3 or higher neutropenia and/or neutropenic complications (eg, febrile neutropenia, neutropenic infection, or sepsis) compared with triweekly CBZ, 25 mg/m2 (triweekly CBZ25), plus G-CSF (standard regimen).

Design, Setting, And Participants: A total of 196 patients 65 years or older with progressive mCRPC were enrolled in this prospective phase 3 randomized clinical trial conducted in France (18 centers) and Germany (7 centers) between May 5, 2017, and January 7, 2021.

Article Synopsis
  • Early relapse in stage III colon cancer patients, particularly those with proficient mismatch repair (pMMR) and RAS or BRAF mutations, is linked to poorer survival rates after recurrence.
  • * Patients with deficient mismatch repair (dMMR) had fewer recurrences but a shorter median time to recurrence compared to pMMR patients, highlighting the role of molecular status in recurrence patterns.
  • * The study suggests that early relapse significantly impacts survival, especially for those with specific genetic mutations, underlining the importance of molecular profiling in treatment strategies for colon cancer patients.

Background: Several cancer immunotherapies that target the PD-L1/PD-1 pathway show promising clinical activity in patients with hepatocellular carcinoma (HCC). However, the standard of care in first-line treatment with atezolizumab (anti-PD-L1 therapy) in combination with bevacizumab is associated with a limited objective response rate. Telomerase reverse transcriptase (TERT) activation meets the criteria of oncogenic addiction in HCC and could be actionable therapeutic target and a relevant tumor antigen.

  • Tumor size (TS) impacts intraoperative outcomes in laparoscopic major hepatectomy (L-MH), with this study aiming to clarify its effects and find optimal TS cutoffs for assessing surgical difficulty.
  • The analysis, which included 1396 patients from a larger pool of 3008 undergoing L-MH, identified two critical TS cutoffs at 50 mm and 100 mm that segmented patients into three distinct groups.
  • Results showed that larger TS correlated with increased open conversion rates, longer operation times, higher blood loss, and more intraoperative blood transfusions, while postoperative complications remained similar across the groups.

Article Synopsis
  • This study aimed to compare outcomes of robotic limited liver resections (RLLR) and laparoscopic limited liver resections (LLLR) for tumors in the posterosuperior liver segments, noting that previous research had not thoroughly examined the differences in performance and safety between the two approaches.
  • An analysis of data from 3510 patients showed that RLLR had significant advantages over LLLR, including a lower rate of open conversions, reduced blood loss, and shorter operative times, even in patients with cirrhosis.
  • Despite the improved perioperative outcomes for RLLR, postoperative metrics like readmission, morbidity, and mortality rates were similar between both surgical techniques.

Background: The impact of cirrhosis and portal hypertension on perioperative outcomes of minimally invasive left lateral sectionectomies remains unclear. We aimed to compare the perioperative outcomes between patients with preserved and compromised liver function (noncirrhotics versus Child-Pugh A) when undergoing minimally invasive left lateral sectionectomies. In addition, we aimed to determine if the extent of cirrhosis (Child-Pugh A versus B) and the presence of portal hypertension had a significant impact on perioperative outcomes.
