A study comparing transanal endoscopic microsurgery (TEM) and single-port robotic transanal minimally invasive surgery (SP rTAMIS) for rectal lesion excision found that SP rTAMIS offers shorter operative times and lower postoperative morbidity. Both methods had similar rates of positive margins and piecemeal resection, with no intraoperative complications in either cohort. SP rTAMIS had fewer postoperative complications (9% vs. 20%, p = 0.031) and no mortalities. These findings support SP robotics as a promising alternative to TEM for rectal lesion excision.

Robotic Pelvic Lymph Node Dissection in Advanced Rectal Cancer
A recent meta-analysis compared robotic pelvic lateral lymph node dissection (LPLND) to laparoscopic LPLND in patients with advanced rectal cancer. The study found that robotic surgery led to more pelvic lymph nodes being harvested and fewer complications, especially regarding urinary retention, despite longer operation times. This suggests potential advantages of robotic over laparoscopic techniques in this context. Further research is needed to strengthen these findings, but the results indicate that robotic surgery could be a valuable option in treating advanced rectal cancer.

Predictive Factors for Better Outcomes in Peritoneal Metastasis of Gastric Cancer
A new study has identified significant predictive factors for patients with peritoneal metastasis of gastric cancer (PMGC) who underwent aggressive treatment strategies. The study focused on patients who received a combination of cytoreductive surgery (C-CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) after responding to induction chemotherapy.
Key findings include:
Patients with a Ki-67 index lower than 10 had significantly better recurrence-free and overall survival.
Limited lymph node involvement (LNI < 2) and smaller omental lesion size (< 0.5 cm) were associated with improved outcomes.
The study retrospectively examined 62 patients and found that those with these favorable parameters had a higher likelihood of long-term survival. Cox regression analysis further confirmed that decreased Ki-67 expression and minimal lymph node involvement were independent factors for better prognosis.
These results underscore the importance of thorough preoperative assessment to identify patients who are likely to benefit most from an aggressive multimodal treatment approach. This approach includes initial induction chemotherapy, followed by surgery and HIPEC, and aims to maximize survival outcomes.

New Insights in Treating Malignant Peritoneal Mesothelioma
Malignant peritoneal mesothelioma (MPeM) is a rare and aggressive cancer of the abdominal lining. A recent multi-center study has shed light on the effectiveness of various treatments for this condition. The study divided patients into two groups: those who underwent cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) and those who could not undergo curative surgery.
The CRS-HIPEC group showed significantly better outcomes, with a median overall survival (OS) of 44.6 months compared to 12.6 months for non-surgical treatments. This combination therapy is particularly beneficial for patients who can achieve complete or near-complete tumor resection. Factors such as low completeness of cytoreduction (CC) scores and low peritoneal cancer index (PCI) scores were associated with better survival rates.
For patients who are not surgical candidates, chemotherapy remains the primary treatment option. The platinum-pemetrexed regimen is particularly effective, with patients showing improved progression-free survival (PFS) and OS compared to other treatments.
The study underscores the importance of personalized treatment plans based on the patient’s specific condition and prognosis. It also highlights the role of experienced surgical centers in achieving optimal outcomes. Continuous advancements in surgical techniques and chemotherapy regimens are improving survival rates for MPeM patients.

Management of T1 Colon Cancer: Insights from Denmark
In Denmark, the management of T1 colon cancer emphasizes the importance of complete endoscopic resection (R0 resection) with clear horizontal and vertical margins, and no lymphovascular invasion. This approach is designed to ensure that the histopathology can accurately confirm the absence of high-risk features, minimizing the need for additional surgeries. The key focus is on obtaining a sufficient amount of submucosal tissue during the resection for better diagnostic accuracy. These practices help enhance patient outcomes by reducing the likelihood of recurrence and the necessity for further invasive procedures.
Enhancing Quality of Life in Hepatocellular Carcinoma: Insights from the HIMALAYA Study
The Phase III HIMALAYA study provides new insights into the management of unresectable hepatocellular carcinoma (uHCC), highlighting the benefits of the Single Tremelimumab Regular Interval Durvalumab (STRIDE) regimen over sorafenib. This study involved 1,171 patients who were evaluated for patient-reported outcomes (PROs), including global health status, quality of life (QoL), and symptom burden.
The STRIDE regimen significantly extended the time to deterioration in global health status, physical functioning, and various symptoms compared to sorafenib. Patients on STRIDE and Durvalumab also had a higher likelihood of clinically meaningful improvements in QoL, role functioning, and symptom management.
These findings suggest that STRIDE not only improves overall survival but also enhances the quality of life for patients with uHCC, making it a compelling frontline treatment option. General practitioners should consider these benefits when discussing treatment plans with patients, as improving QoL is crucial in managing advanced cancers.
The comprehensive assessment of PROs and high compliance rates in the HIMALAYA study reinforce the robustness of these results, ensuring that the benefits observed are representative of a diverse patient population.
