Background: Gastric cancer is increasing worldwide and one million new cases were estimated globally in 2020. Use of the laparoscopic approach is increasing especially for subtotal gastrectomy. However, to date, solid data on locally advanced bulky tumors are lacking. The aim of this study is to assess the role of laparoscopic surgery in bulky gastric tumors.
Methods: We performed an observational retrospective single-center analysis. The following data were collected and analyzed for each patient: demographics, tumor-related data, intra-operative data, peri-operative data, and pathological data. Statistical analysis was conducted, including descriptive statistics and chi-squared test, to analyze the differences between categorical variables.
Results: O the 116 patients who underwent gastric surgery, 49 patients were included in the study protocol. All patients had bulky gastric tumors. Eighteen patients underwent laparoscopic gastrectomy and 31 open gastrectomy. The median number of lymph nodes removed was 28.5 (15-46) in the laparoscopic group and 23.05 (6-62) in the open group ( = 0.04). In total, 5.6% of patients of the laparoscopic group had <16 lymph nodes harvested and 35.5% in the open group ( = 0.035). No statistical differences were found between the open and laparoscopic groups in terms of surgical margins ( = 0.69).
Conclusions: Laparoscopic surgery is still a subject of debate in locally advanced bulky gastric cancer. Limited data are available concerning Western patients. This study showed superiority in terms of the quality of lymphadenectomy and non-inferiority in terms of radical resection margins.

Comparison of clinical features of patients with or without severe gastrointestinal complications in aggressive gastrointestinal lymphomas.
World J Gastrointest Oncol

Article Synopsis
- Aggressive primary gastrointestinal non-Hodgkin lymphoma (PGINHL) is a rare type of cancer that often leads to serious gastrointestinal complications (GICs), with a significant portion of patients experiencing these issues.
- A study analyzed 124 aggressive PGINHL cases to compare patients with GICs to those without, identifying risk factors and treatment outcomes through statistical methods like Logistic regression and Kaplan-Meier survival analysis.
- Findings revealed that nearly half of the patients had GICs, with diffuse large B-cell lymphoma being the most common type, and specific risk factors such as the tumor's location in the small intestine and size were important for predicting complications.
Short-term outcomes of a phase II trial of perioperative capecitabine plus oxaliplatin therapy for advanced gastric cancer with extensive lymph node metastases (OGSG1701).
Gastric Cancer

Frontier Science for Cancer and Chemotherapy, Osaka University Graduate School of Medicine, Suita, Japan.
Background: The prognosis of advanced gastric cancer (GC) with extensive lymph node (LN) metastasis treated with surgery alone remains poor. We conducted a multicenter phase II study to evaluate the efficacy and safety of perioperative capecitabine plus oxaliplatin (CapeOx) therapy in patients with advanced GC with extensive LN metastases.
Patients And Methods: Patients with histologically proven HER2-negative or unknown gastric adenocarcinoma with paraaortic LN (PALN) metastases and/or bulky LN metastases located at the celiac axis, common hepatic artery, and/or splenic artery were included in the study.
Bulky Isolated Adrenal Metastasis as First Presentation of Occult Hepatocellular Carcinoma (HCC) in a Patient with a Synchronous Squamous Carcinoma of the Tongue.

Article Synopsis
- - A 72-year-old male with a history of advanced tongue cancer was found to have a large left adrenal mass during follow-up, which raised suspicion for metastasis.
- - After surgical removal, the mass was diagnosed as poorly differentiated hepatocellular carcinoma (HCC), despite no primary liver tumor being identified during further investigations.
- - The case highlights the importance of considering adrenal metastasis in cancer patients, as it can lead to the unexpected discovery of another underlying malignancy, such as HCC, especially in the context of liver cirrhosis.
Outcomes and toxicities in patients with diffuse-large B cell lymphoma involving the gastrointestinal tract and digestive organs.

Department of Radiation Oncology, The University of Texas MD Anderson Cancer Center, Houston, TX, United States.
Background: Diffuse large B-cell lymphoma (DLBCL) involving the gastrointestinal (GI) organs is rare, and real-world outcomes after combined modality therapy (CMT) with systemic therapy (ST) and radiotherapy (RT) are not well-characterized, particularly in the contemporary era. We characterized outcomes in a large cohort of GI-DLBCL patients treated with ST alone or CMT.
Methods: Patients with GI-DLBCL treated at a single institution were retrospectively reviewed.
Para-aortic lymph node dissection following neoadjuvant chemotherapy for type 4 or large type 3 gastric cancer with extensive lymph node metastasis.
World J Surg
October 2024
Gastric Surgery Division, National Cancer Center Hospital, Tokyo, Japan.
Background: D2 and para-aortic lymph node dissection (PAND) following neoadjuvant chemotherapy (NAC) are reportedly effective for gastric cancer (GC) with extensive lymph node metastasis (ELM), such as para-aortic nodal metastasis or bulky nodal metastasis, around the major perigastric arteries. However, type 4 and large type 3 tumors were excluded from previous studies, as they are considered special subtypes that easily spread to the peritoneum. Whether or not PAND contributes to the survival of type 4 or large type 3GC with ELM is thus unclear.
