A woman in her early 80 s was followed up in our hospital for chronic hepatitis C after viral eradication. We detected rapid-growing lymph node metastasis of hepatocellular carcinoma (HCC) after treatment with transcatheter arterial chemoembolization and/or radiofrequency ablation. We found that the metastasis was operable, but the size and location of the metastasis obliged the patient to receive pancreatoduodenectomy, which was too invasive. Then we initiated systemic chemotherapy to perform radical minimally invasive surgery. We treated the patient with 3 weekly cycles of atezolizumab 1200 mg plus bevacizumab 15 mg/kg. The patient tolerated the treatment well, and treatment-emergent adverse events included deterioration of hypertension and increased uric protein. After a total of 4 cycles of therapy, abdominal computed tomography findings showed that the metastasis evidently decreased, and a complete response was achieved based on the Revised Response Evaluation Criteria in Solid Tumors (RECIST) guidelines (version 1.1). Seventeen days later, the metastasis was dissected. Subsequently, we confirmed that there was no pathological metastatic lesion in the resected lymph node. Our case is the first report of successful application of the radical therapy to lymph node metastasis of HCC via combination therapy with atezolizumab/bevacizumab.

BACKGROUND: The oncological outcomes of fertility-sparing surgery (FSS) compared to radical surgery (RS) in patients with stage I epithelial ovarian cancer (EOC) remain a subject of debate. We evaluated the risk ratios (RRs) for outcomes in patients with stage I EOC who underwent FSS versus RS.
METHODS: We conducted a systematic search of PubMed, Web of Science, and Embase for articles published up to November 29, 2023. Studies that did not involve surgical procedures or included pregnant patients were excluded. We calculated the RRs for disease-free survival, overall survival, and recurrence rate. The quality of the included studies was assessed using the Cochrane Risk of Bias in Nonrandomized Studies of Interventions (ROBINS-I) tool. The meta-analysis was registered on PROSPERO (CRD42024546460).
RESULTS: From the 5,529 potentially relevant articles, we identified 83 articles for initial screening and included 12 articles in the final meta-analysis, encompassing 2,906 patients with epithelial ovarian cancer. There were no significant differences between the two groups in disease-free survival (RR [95% confidence interval {CI}], 0.90 [0.51, 1.58]; P = 0.71), overall survival (RR [95% CI], 0.74 [0.53, 1.03]; P = 0.07), and recurrence rate (RR [95% CI], 1.10 [0.69, 1.76]; P = 0.68). In sensitivity analyses, the significant difference was observed only for overall survival (before exclusion: RR [95% CI], 0.74 [0.53-1.03], P = 0.07; after exclusion: RR [95% CI], 0.70 [0.50-0.99]; P = 0.04).
CONCLUSIONS: This is the first and only individual patient data meta-analysis comparing disease-free survival, overall survival, and recurrence rate of patients with early-stage epithelial ovarian cancer undergoing FSS and RS. FSS was associated with similar disease-free survival and risk of recurrence as RS. We hypothesized that the decreased overall survival in the FSS group could not be attributed to distant metastases from epithelial ovarian cancer.

OBJECTIVE: In the treatment of early-stage rectal cancer, a growing number of studies have shown that transanal endoscopic microsurgery is one of the alternatives to radical surgery adhering to total mesorectal excision that can reduce the incidence of adverse events without compromising treatment outcomes. The purpose of this meta-analysis is to compare the safety and treatment effect of transanal endoscopic microsurgery and radical surgery adhering to total mesorectal excision to provide a basis for clinical treatment selections.
METHODS: We searched the literatures of four major databases, PubMed, Embase, Web of science, and Cochrane Library, without limitation of time. The literatures included randomized controlled studies and cohort studies comparing two surgical procedures of transanal endoscopic microsurgery and radical surgery adhering to total mesorectal excision. Treatment effectiveness and safety results of transanal endoscopic microsurgery and radical surgery were extracted from the included literatures and statistically analyzed using RevMan5.4 and stata17.
RESULTS: Ultimately, 13 papers were included in the study including 5 randomized controlled studies and 8 cohort studies. The results of the meta-analysis showed that the treatment effect and safety of both transanal endoscopic microsurgery and radical surgery in distant metastasis (RR, 0.59 (0.34, 1.02), P > 0.05), overall recurrence (RR, 1.49 (0.96, 2.31), P > 0.05), disease-specific-survival (RR, 0.74 (0.09, 1.57), P > 0.05), dehiscence of the sutureline or anastomosis leakage (RR, 0.57 (0.30, 1.06), P > 0.05), postoperative bleeding (RR, 0.47 (0.22, 0.99), P > 0.05), and pneumonia (RR, 0.37, (0.10, 1.40), P > 0.05) were not significantly different. However, they differ significantly in perioperative mortality (RR, 0.26 (0.07, 0.93, P < 0.05)), local recurrence (RR, 2.51 (1.53, 4.21), P < 0.05),_overall survival_ (RR, 0.88 (0.74, 1.00), P < 0.05), disease-free-survival (RR, 1.08 (0.97, 1.19), P < 0.05), temporary stoma (RR, 0.05 (0.01, 0.20), P < 0.05), permanent stoma (RR, 0.16 (0.08, 0.33), P < 0.05), postoperative complications (RR, 0.35 (0.21, 0.59), P < 0.05), rectal pain (RR, 1.47 (1.11, 1.95), P < 0.05), operation time (RR, -97.14 (-115.81, -78.47), P < 0.05), blood loss (RR, -315.52 (-472.47, -158.57), P < 0.05), and time of hospitalization (RR, -8.82 (-10.38, -7.26), P < 0.05).
CONCLUSIONS: Transanal endoscopic microsurgery seems to be one of the alternatives to radical surgery for early-stage rectal cancer, but more high-quality clinical studies are needed to provide a reliable basis.

To assess bowel function in women with deep infiltrating endometriosis according to surgical approach (radical vs conservative).
Five databases were searched from 1970 to September 2021 to retrieve studies comparing radical (colorectal segmental resection) and conservative (shaving or discoid excision) surgery for bowel function in women with deep infiltrating endometriosis.
No language restriction was applied. Two reviewers extracted and combined data from the included studies, applying a meta-analytic model with random effects in all calculations. Results are expressed in risk ratio (RR) with 95% confidence interval (CI). Assessment of risk of bias and quality of evidence was performed by the Newcastle-Ottawa and Grading of Recommendations, Assessment, Development and Evaluation, respectively.
We included 13 studies in our meta-analysis, and most of them were of nonrandomized design. Conservative surgery had fewer events of constipation and frequent bowel movements when compared with radical surgery (RR, 2.31; 95% CI, 1.21-4.43; I2 = 0%; 3 studies; RR, 2.80; 95% CI 1.17-6.75; I2 = 0%; 2 studies, respectively). Defecation pain, anal incontinence loss, minor and major lower anterior resection syndrome, and Clavien-Dindo complications grade I to IV showed no statistically significant difference between surgeries. Grading of Recommendations, Assessment, Development and Evaluation assessment was low to very low for all outcomes.
Conservative surgery (shaving or discoid excision) presented fewer events of constipation and frequent bowel movements than colorectal segmental resection. There was a very low quality of evidence to provide recommendations regarding bowel function.

Cervical cancer (CC) remains a public health issue worldwide despite preventive measures. Surgical treatment in the early-stage CC has evolved during the last decades. Our aim was to review the advances in the literature and summarize the ongoing studies on this topic. To this end, we conducted a literature review through PubMed focusing on English-language articles on the surgical management of early-stage CC. The emergent topics considered here are the FIGO 2018 staging system update, conservative management with less radical procedures for selected patients, lymph node staging, fertility preservation, preferred surgical approach, management of tumors up to 2 cm, and prognosis. In terms of updating FIGO, we highlight the inclusion of lymph node status on staging and the possibility of imaging. Regarding the preferred surgical approach, we emphasize the LACC trial impact worldwide in favor of open surgery; however, we discuss the controversial application of this for tumors < 2 cm. In summary, all topics show a tendency to provide patients with tailored treatment that avoids morbidity while maintaining oncologic safety, which is already possible in high-income countries. We believe that efforts should focus on making this a reality for low-income countries as well.

Sister Mary-Joseph nodule (NSMJ) is a cutaneous metastasis of the umbilicus, rare and accounts for 2-3% of the patients with advanced stages of colorectal adenocarcinoma. Here we report the observation of a 48-year-old Moroccan man, referred to our hospital to manage a painful ulcero-budding nodule of the umbilicus; computed tomography revealed that the processes infiltrated the urachus and the bladder. Laboratory parameters were normal and radical surgery was performed to remove the tumor and embryological remnant of the umbilicus. The histological assessment confirmed the sigmoidal origin of the umbilical nodule. This kind of disease always poses a problem of treatment. It was considered for a long time as an outdated stage of tumor disease that deserves just palliative treatment. Several cases published in the international literature with radical treatment had good survival and evolution, which gives hope to patients with this disease.

Ovarian cancer (OC) is the most lethal gynecological malignancy and very little is known about the underlying tumorigenesis mechanisms. For other tumors, like colorectal cancer, a relationship between several opportunistic pathogens and cancer development and progression has been proven. Recent researches also underline a possible correlation between gut microbiota dysbiosis and cancer treatment efficacy and adverse effects. Several studies have also demonstrated a link between abdominal surgery and gut microbiota modifications. In this paper, we aim to review the available evidences of this issue in OC to understand if there is a relationship between gut microbiota modifications and efficacy and adverse effects of cancer therapies, either surgical and medical treatments. Well-designed clinical studies, with a robust translational component, are required to better understand the modulation of gut microbiota during OC treatment. The microbiota/microbiome composition analysis, in the near future, could represent a novel instrument to personalize anticancer therapies.

OBJECTIVE: We aimed to compare the safety and oncological outcomes of transanal endoscopic microsurgery (TEM) and radical surgery (RS) for patients with T1 or T2 rectal cancer.
METHODS: We searched Pubmed, Embase, Cochrane Library databases for relevant studies comparing TEM with RS in rectal cancer published until April 2020. We focused on safety and oncological outcomes.
RESULTS: This meta-analysis included 3526 patients from 12 studies. Compared with RS, TEM had a shorter operative time (weighted mean difference [WMD] -110.02, 95% confidence interval [CI]: 143.98, -76.06), less intraoperative blood loss (WMD -493.63, 95% CI: 772.66, -214.59), lower perioperative morality (risk ratio [RR] 0.25, 95% CI: 0.06, 0.99), and fewer postoperative surgical complications (RR 0.23, 95% CI: 0.11,0.45). TEM was associated with more patients with a positive margin or a doubtfully complete margin than RS (RR 7.36, 95% CI: 3.66, 14.78). TEM was associated with higher local recurrence (RR 2.63, 95% CI: 1.60, 4.31) and overall recurrence (RR 1.60, 95% CI: 1.09, 2.36). TEM had a negative effect on 5-year overall survival (hazard ratio [HR] 1.51, 95% CI: 1.16, 1.96), especially in the T2 without neoadjuvant therapy (NAT) subgroup (HR 2.02, 95% CI: 1.32, 3.09), but in the subgroups of T1 or T2 with NAT before TEM, TEM did not yield a significantly lower overall survival than RS.
CONCLUSIONS: TEM seems appropriate for T1 rectal cancer with favourable histopathology. For patients with T2 rectal cancer, NAT before TEM may contribute to achieving oncological outcomes equivalent to that achieved with RS.
