RESUMO
INTRODUCTION: The MonarchE trial explored the use of abemaciclib, a CDK4/6 inhibitor, as an adjuvant treatment in high-risk early-stage luminal-like breast cancer. The study's inclusion criteria, especially the N2 status, may require revisiting surgical interventions, including invasive axillary lymph node dissection (ALND)-a procedure that current guidelines generally do not recommend. METHODS: We conducted a single-centre, retrospective, observational cohort study on non-metastatic breast cancer patients managed from 2002 to 2011, at the Institut Curie. Data collection involved clinical and histological characteristics plus treatment follow-up. RESULTS: Out of 8715 treated patients, 721 met the inclusion criteria. Overall, 12% (87) were classified as N2 ( ≥ 4 positive lymph nodes), thus eligible for abemaciclib per "node criterion." Tumour size, positive sentinel lymph nodes, and lobular histology showed a significant correlation with N2 status. Approximately 1000 ALNDs would be required to identify 120 N2 cases and prevent four recurrences. CONCLUSION: The MonarchE trial may significantly affect surgical practices due to the need for invasive procedures to identify high-risk patients for adjuvant abemaciclib treatment. The prospect of unnecessary morbidity demands less invasive N2 status determination methods. Surgical decisions must consider patient health and potential treatment benefits.

PURPOSE: We aimed to evaluate whether neoadjuvant chemotherapy (NAC) could be a risk factor for breast cancer-related lymphedema (BCRL) associated with axillary lymph node dissection (ALND). PATIENTS AND METHODS: A total of 596 patients with cT0-4N0-3M0 breast cancer who underwent ALND and chemotherapy were retrospectively analyzed between March 2012 and March 2022. NAC was administered in 188 patients (31.5%), while up-front surgery in 408 (68.5%). Univariate and multivariable Cox regression analyses were performed to determine whether NAC was an independent risk factor for BCRL. With propensity score matching (PSM), the NAC group and up-front surgery group were matched 1:1 by age, body mass index (BMI), molecular subtypes, type of breast surgery, and the number of positive lymph nodes. Kaplan-Meier survival analyses were performed for BCRL between groups before and after PSM. Subgroup analyses were conducted to explore whether NAC differed for BCRL occurrence in people with different characteristics. RESULTS: At a median follow-up of 36.3 months, 130 patients (21.8%) experienced BCRL [NAC, 50/188 (26.60%) vs. up-front surgery, 80/408 (19.61%); P = 0.030]. Multivariable analysis identified that NAC [hazard ratio, 1.503; 95% CI (1.03, 2.19); P = 0.033] was an independent risk factor for BCRL. In addition, the hormone receptor-negative/human epidermal growth factor receptor 2-negative (HR-/HER2-) subtype, breast-conserving surgery (BCS), and increased positive lymph nodes significantly increased BCRL risk. After PSM, NAC remained a risk factor for BCRL [hazard ratio, 1.896; 95% CI (1.18, 3.04); P = 0.007]. Subgroup analyses showed that NAC had a consistent BCRL risk in most clinical subgroups. CONCLUSION: NAC receipt has a statistically significant increase in BCRL risk in patients with ALND. These patients should be closely monitored and may benefit from early BCRL intervention.

PURPOSE OF REVIEW: The most common surgical procedure associated with lymphedema formation is the regional lymphadenectomy. One of the advantages of sentinel node biopsy is the reduction of the risk of lymphedema formation. The purpose of this review is to collect and analyze the most relevant and recent evidence of the use of sentinel node biopsy and its implication on the development of postoperative lymphedema in gynecological cancer. RECENT FINDINGS: The current evidence of the use of sentinel node biopsy in cervical cancer to reduce lymphedema is heterogeneous and more data is needed to establish its role.Sentinel lymph node biopsy in endometrial cancer is a staging procedure with lower surgical complications, as well as lymphedema formation; while the results of prospective trials evaluating its impact on quality of life are still lacking.Sentinel lymph node biopsy in vulvar cancer minimizes the need for extensive dissection and reduces the incidence of complications associated with overharvesting of lymph nodes such as lymphedema without compromising oncological outcomes. SUMMARY: The prevalence of lymphedema in gynecological cancer varies based on the surgical treatment or additional therapies applied. Over the past years, one of the most important surgical modifications to decrease lymphedema formation has been implementation of sentinel lymph node technique mainly in vulvar cancer patients.

PURPOSE: Primary surgical treatment with retroperitoneal lymph node dissection aims to accurately stage and treat patients with node-positive pure seminoma while avoiding long-term risks of chemotherapy or radiation, traditional standard-of-care treatments. MATERIALS AND METHODS: We reported the pathologic and oncologic outcomes of patients with pure seminoma treated with primary retroperitoneal lymph node dissection in a retrospective, single-institution case series over 10 years. The primary outcome was 2-year recurrence-free survival stratified by adjuvant management strategy (surveillance vs adjuvant chemotherapy). RESULTS: Forty-five patients treated with primary retroperitoneal lymph node dissection for pure testicular seminoma metastatic to the retroperitoneum were identified. Median size of largest lymph node before surgery was 1.8 cm. Viable germ cell tumor, all of which was pure seminoma, was found in 96% (n=43) of patients. The median number of positive nodes and nodes removed was 2 and 54, respectively. Median positive pathologic node size was 2 cm (IQR 1.4-2.5 cm, range 0.1-5 cm). Four of 29 patients managed with postoperative surveillance experienced relapse; 2-year recurrence-free survival was 81%. Median follow-up for those managed with surveillance who did not relapse was 18.5 months. There were no relapses in the retroperitoneum, visceral recurrences, or deaths. Among the 16 patients who received adjuvant treatment, 1 patient experienced relapse in the pelvis at 19 months. CONCLUSIONS: Primary retroperitoneal lymph node dissection for pure seminoma with low-volume metastases to the retroperitoneum is safe and effective, allowing most patients to avoid long-term toxicities from chemotherapy or radiation.

BACKGROUND: Identification of risk factors facilitates the prevention of breast cancer-related lymphedema (BCRL). Several published systematic reviews have already addressed the risk factors for BCRL. This study aimed to systematically identify potential risk factors for BCRL and evaluate the quality of evidence. METHODS: The study followed methodologic guidance from the Joanna Briggs Institute, and the Cochrane Handbook. The following electronic databases were systematically searched from inception to 15 November 2022: PubMed, Embase, CINAHL, Web of Science, Scopus, CNKI, SinoMed, Wanfang, JBI Database, Cochrane Database, ProQuest, and PROSPERO. Two authors independently screened studies, extracted data, and assessed methodologic quality using AMSTAR2, risk of bias using ROBIS, and evidence quality using GRADE. The study evaluated overlap, assessed the small-study effect, and calculated the I2 statistic and Egger's P value as needed. RESULTS: The study included 14 publications comprising 10 meta-analyses and 4 systematic reviews. The authors identified 39 factors and 30 unique meta-analyses. In the study, 13 innate personal trait-related risk factors, such as higher body mass index (BMI) and axillary lymph nodes dissection, showed statistically significant associations with BCRL incidence. Breast reconstruction was found to be a protective factor. The methodologic quality was low or critically low. The majority of the systematic reviews and/or meta-analyses were rated as having a high risk of bias. Evidence quality was low for 22 associations and moderate for 8 associations. CONCLUSIONS: The currently identified risk factors for BCRL all are innate personal trait-related factors. Future well-designed studies and robust meta-analyses are needed to explore potential associations between behavioral-, interpersonal-, and environmental-related factors and BCRL, as well as the role of genetic variations and pathophysiologic factors.

BACKGROUND: Understanding long-term arm symptoms in breast cancer survivors is critical given excellent survival in the modern era. METHODS: This cross-sectional study included patients treated for stage 0-III breast cancer at our institution from 2002 to 2012. Patient-reported arm symptoms were collected from the EORTC QLQ-BR23 questionnaire. We used linear regression to evaluate adjusted associations between locoregional treatments and the continuous Arm Symptom (AS) score (0-100; higher score reflects more symptoms). RESULTS: A total of 1126 patients expressed interest in participating and 882 (78.3%) completed the questionnaire. Mean time since surgery was 10.5 years. There was a broad distribution of locoregional treatments, including axillary lymph node dissection (ALND) in 37.1% of patients, mastectomy with reconstruction in 36.5% of patients, and post-mastectomy radiation in 38.2% of patients. Overall, 64.3% (95% confidence interval [CI] 61.1-67.4%) of patients reported no arm symptoms, 17.0% (95% CI 14.7-19.6%) had one mild symptom, 9.4% (95% CI 7.7-11.5%) had two or more mild symptoms, and 9.3% (95% CI 7.6-11.4%) reported one or more severe symptoms. Adjusted AS scores were significantly higher with ALND versus sentinel node biopsy (ß 3.5, p = 0.01), and with autologous reconstruction versus all other breast/reconstructive surgery types (ß 4.5-5.5, all p < 0.05). There was a significant interaction between axillary and breast/reconstructive surgery, with the greatest effect of ALND in those with mastectomy with implant (ß 9.7) or autologous (ß 5.7) reconstruction. CONCLUSIONS: One in three patients reported arm symptoms at a mean of 10 years from treatment for breast cancer, although rates of severe symptoms were low (<10%). Attention is warranted to the arm morbidity related to both axillary and breast surgery during treatment counseling and survivorship.

BACKGROUND: The Evaluation of Groin Lymphadenectomy Extent for Melanoma (EAGLE FM) study sought to address the question of whether to perform inguinal (IL) or ilio-inguinal lymphadenectomy (I-IL) for patients with inguinal nodal metastatic melanoma who have no clinical or imaging evidence of pelvic disease. Primary outcome measure was disease-free survival at 5 years, and secondary endpoints included lymphoedema. METHODS: EAGLE FM was designed to recruit 634 patients but closed with 88 patients randomised because of slow recruitment and changes in melanoma management. Lymphoedema assessments occurred preoperatively and at 6, 12, 18, and 24 months postoperatively. Lymphoedema was defined as Inter-Limb Volume Difference (ILVD) > 10%, Lymphoedema Index (L-Dex®) > 10 or change of L-Dex® > 10 from baseline. RESULTS: Prevalence of leg lymphoedema between the two groups was similar but numerically higher for I-IL at all time points in the first 24 months of follow-up; highest at 6 months (45.9% IL [CI 29.9-62.0%], 54.1% I-IL [CI 38.0-70.1%]) and lowest at 18 months (18.8% IL [CI 5.2-32.3%], 41.4% I-IL [CI 23.5-59.3%]). Median ILVD at 24 months for those affected by lymphoedema was 14.5% (IQR 10.6-18.7%) and L-Dex® was 12.6 (IQR 9.0-17.2). There was not enough statistical evidence to support associations between lymphoedema and extent of surgery, radiotherapy, or wound infection. CONCLUSIONS: Despite a trend for patients who had I-IL to have greater lymphoedema prevalence than IL in the first 24 months after surgery, our study's small sample did not have the statistical evidence to support an overall difference between the surgical groups.

BACKGROUND: Breast cancer-related lymphedema (BCRL) remains a significant post-surgical complication of breast cancer treatment. Immediate lymphatic reconstruction (ILR) at the time of axillary lymph node dissection (ALND) has shown promise in preventing BCRL. While the primary literature supporting ILR comes from academic institutions, the majority of breast cancer care in the USA occurs in the community setting. This study evaluated a preventative lymphedema program performing ILR at a community health system. PATIENTS AND METHODS: A prospective database including all patients who underwent ALND with concurrently attempted ILR from 2019 to 2021 was retrospectively reviewed. The historical benchmark lymphedema rate was calculated through retrospective review of electronic medical records for all patients who underwent ALND without ILR from 2011 to 2021. RESULTS: Ninety patients underwent ALND with ILR, of which ILR was successful in 69 (76.7%). ILR was more likely to be aborted in smokers (p < 0.05) and those with fewer lymphatic channels (p < 0.05) or a higher body mass index (BMI) (p = 0.08). Patients with successful versus aborted ILR had lower lymphedema rates (10.9% versus 66.7%, p < 0.01) and improved Disability of the Arm, Shoulder, and Hand (DASH) scores (8.7 versus 19.8, p = 0.25), and lower lymphedema rates than the historical benchmark (10.9% versus 50.2%, p < 0.01). Among patients with successful ILR, older patients were more likely to develop lymphedema (p < 0.05). CONCLUSIONS: Successful ILR after ALND significantly reduced the lymphedema rate when compared with patients with aborted ILR and our institution's historical benchmark. Our experience supports the efficacy of ILR and highlights the feasibility of ILR within a community health system.

BACKGROUND: Breast cancer-related lymphedema (BCRL) poses a significant risk following sentinel lymph node biopsy (SLNB) and axillary lymph node dissection (ALND), particularly affecting ethnic minorities, with a twofold increased risk. Axillary reverse mapping (ARM), a novel technique, shows potential in reducing BCRL rates, yet its utility in ethnic minorities lacks sufficient exploration. Therefore, our study aims to investigate the utility and outcomes of ARM on BCRL in an ethnic diverse group. METHODS: A retrospective chart review of ARM patients from January 2019 to July 2022 was conducted, monitoring patients over 24 months at 3-month intervals using SOZO® scores, with comparisons with preoperative baselines. RESULTS: Of the 212 patients, 83% belonged to ethnic minorities. SLNB was performed in 83%, ALND in 17%, and 62.3% underwent radiation therapy. Positive lymph nodes were found in 31.6%, with 22.2% exhibiting blue nodes and 25.9% exhibiting blue lymphatics. Of identified blue nodes, 70.2% were excised, including 51.5% crossover nodes. Lymphedema occurred in 3 patients, resulting in a BCRL rate of 1.4%. Compared with an historical BCRL incidence of 40.4% following ALND in ethnic minorities, our study reported a significantly lower rate of 8% (p < 0.001). CONCLUSION: The ARM procedure can significantly lower BCRL in ethnic minority groups. The combination of ARM and bioimpedance spectroscopy led to a remarkably low BCRL rate of 1.4%. Notably, none of the patients in our study developed an axillary recurrence at 24-month follow-up. Nevertheless, future studies with larger sample sizes are warranted to better understand the utility of the ARM technique in this population.

BACKGROUND: Surgery for oesophageal squamous cell carcinoma involves dissecting lymph nodes along the recurrent laryngeal nerve. This is technically challenging and injury to the recurrent laryngeal nerve may lead to vocal cord palsy, which increases the risk of pulmonary complications. The aim of this study was to compare the efficacy and safety of robot-assisted oesophagectomy (RAO) versus video-assisted thoracoscopic oesophagectomy (VAO) for dissection of lymph nodes along the left RLN. METHODS: Patients with oesophageal squamous cell carcinoma who were scheduled for minimally invasive McKeown oesophagectomy were allocated randomly to RAO or VAO, stratified by centre. The primary endpoint was the success rate of left recurrent laryngeal nerve lymph node dissection. Success was defined as the removal of at least one lymph node without causing nerve damage lasting longer than 6 months. Secondary endpoints were perioperative and oncological outcomes. RESULTS: From June 2018 to March 2022, 212 patients from 3 centres in Asia were randomized, and 203 were included in the analysis (RAO group 103; VAO group 100). Successful left recurrent laryngeal nerve lymph node dissection was achieved in 88.3% of the RAO group and 69% of the VAO group (P < 0.001). The rate of removal of at least one lymph node according to pathology was 94.2% for the RAO and 86% for the VAO group (P = 0.051). At 1 week after surgery, the RAO group had a lower incidence of left recurrent laryngeal nerve palsy than the VAO group (20.4 versus 34%; P = 0.029); permanent recurrent laryngeal nerve palsy rates at 6 months were 5.8 and 20% respectively (P = 0.003). More mediastinal lymph nodes were dissected in the RAO group (median 16 (i.q.r. 12-22) versus 14 (10-20); P = 0.035). Postoperative complication rates were comparable between the two groups and there were no in-hospital deaths. CONCLUSION: In patients with oesophageal squamous cell carcinoma, RAO leads to more successful left recurrent laryngeal nerve lymph node dissection than VAO, including a lower rate of short- and long-term recurrent laryngeal nerve injury. Registration number: NCT03713749 (http://www.clinicaltrials.gov).
Oesophageal cancer often requires complex surgery. Recently, minimally invasive techniques like robot- and video-assisted surgery have emerged to improve outcomes. This study compared robot- and video-assisted surgery for oesophageal cancer, focusing on removing lymph nodes near a critical nerve. Patients with a specific oesophageal cancer type were assigned randomly to robot- or video-assisted surgery at three Asian hospitals. Robot-assisted surgery had a higher success rate in removing lymph nodes near the important nerve without permanent damage. It also had shorter operating times, more lymph nodes removed, and faster drain removal after surgery. In summary, for oesophageal cancer surgery, the robotic approach may provide better lymph node removal and less nerve injury than video-assisted techniques.

PURPOSE: This study assesses the metastasis rate of the key distal lymph nodes (KDLN) that are not routinely dissected in proximal gastrectomy, aiming to explore the oncological safety of proximal gastrectomy for upper gastric cancer who underwent neoadjuvant chemotherapy. METHODS: We analyzed a cohort of 150 patients with proximal locally advanced gastric cancer (cT3/4 before chemotherapy) from two high-volume cancer centers in China who received preoperative neoadjuvant chemotherapy (NAC) and total gastrectomy with lymph node dissection. Metastasis rate of the KDLN (No.5/6/12a) and the risk factors were analyzed. RESULTS: Key distal lymph node metastasis was detected in 10% (15/150) of patients, with a metastasis rate of 6% (9/150) in No. 5 lymph nodes, 6.7% (10/150) in No. 6 lymph nodes, and 2.7% (2/75) in No. 12a lymph nodes. The therapeutic value index of KDLN as one entity is 5.8. Tumor length showed no correlation with KDLN metastasis, while tumor regression grade (TRG) emerged as an independent risk factor (OR: 1.47; p-value: 0.04). Of those with TRG3 (no response to NAC), 80% (12/15) was found with KDLN metastasis. CONCLUSION: For cT3/4 proximal locally advanced gastric cancer patients, the risk of KDLN metastasis remains notably high even after NAC. Therefore, proximal gastrectomy is not recommended; instead, total gastrectomy with thorough distal lymphadenectomy is the preferred surgical approach.

OBJECTIVES: The incidence of venous thromboembolism (VTE) following radical surgery for vulvar carcinoma remains poorly characterized, and recommendations for postoperative chemoprophylaxis are varied. Our objective was to assess the incidence of postoperative VTE in patients undergoing surgery for vulvar carcinoma and to determine if VTE incidence differs by radical vulvectomy with or without lymph node assessment. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was queried for patients with a diagnosis of vulvar cancer undergoing radical vulvectomy with or without lymph node assessment from 2012 to 2020. Clinical characteristics and 30-day incidence of VTE as well as other postoperative outcomes were abstracted. Variables were compared using Chi-square test and Fischer's exact test, as well as Kruskal-Wallis and Wilcoxon rank sum tests where appropriate. RESULTS: A total of 1672 patients underwent radical vulvectomy for vulvar carcinoma. 11 patients (0.7%) experienced postoperative VTE within 30 days of surgery. The incidence of VTE was similar when radical vulvectomy was performed alone or with lymph node dissection by any method (p = 0.116). Longer operative times (p = 0.033) and greater postoperative length of stay (p = 0.001) were associated with increased risk of postoperative VTE. CONCLUSIONS: The incidence of postoperative VTE is low in patients undergoing radical vulvar surgery in this national cohort. Inguinofemoral lymph node dissection by any method does not appear to be a risk factor for VTE when compared to radical vulvectomy alone. Further research is needed to determine if extended VTE prophylaxis is beneficial in this population.

Early-stage vulvar cancer is managed by a local excision of the primary tumor and, if indicated, a sentinel node (SN) biopsy to assess the need for further groin treatment. With the SN procedure, many patients can be treated less radically and will experience less complications and morbidity compared with an inguinofemoral lymphadenectomy (IFL). Still, the SN procedure can be further optimized. Different tracers for detecting the SN are being investigated, aiming to optimize detection rates and decrease the burden of the procedure and short-term complications. Until now, no standardized protocols exist for the pathologic workup of the SN, possibly leading to discrepancies in detection of metastases between institutes using different methods. New techniques, such as one-step nucleic amplification, seem to have potential in accurately detecting metastases in other cancers, but have not yet been investigated in vulvar squamous cell carcinoma (VSCC). Furthermore, several studies have investigated the possibility to broaden the indications for the SN procedure, such as its use in recurrent disease, larger tumors, or multifocal tumors. Although these studies show encouraging results, cohorts are small and further studies are needed. Prospective studies are currently investigating these subgroups. Lastly, several studies investigated optimization of groin treatment of patients with a metastatic SN. Inguinofemoral radiotherapy is a good alternative to IFL in patients with micrometastases in the SN, with comparable efficacy and less treatment-related morbidity. Reduction of the radicality of groin treatment is also possible in other ways, such as omitting contralateral IFL in patients with lateralized tumors and a unilateral metastatic SN. In conclusion, the SN procedure is an established procedure in early-stage VSCC, although optimization of the technique, pathologic workup, indications, and treatment in the setting of metastatic disease are the subject of ongoing research.

OBJECTIVE: To analyze postoperative ileus rates and postoperative complications between the different pneumoperitoneum settings. The secondary objective was to evaluate narcotic use and intraoperative blood loss between the different pneumoperitoneum settings. METHODS: A prospective, randomized, double blinded study was conducted at pneumoperitoneum pressures of either 12 mmHg or 15 mmHg for patients undergoing robotic assisted radical prostatectomy with bilateral pelvic lymph node dissection by a single high volume surgeon. RESULTS: The risk of ileus in the 12 mmHg group was 1.9% (2/105) compared to 3.2% (3/93) in the 15 mmHg group (OR 0.58, 95%CI 0.1-3.6). There was no difference in the risk of any complication with a complication rate of 4.8% (5/105) in the 12 mmHg arm compared to 4.3% (4/93) in the 15 mmHg arm (OR 1.1, 95% CI 0.3 - 4.3). CONCLUSION: Pneumoperitoneum pressure setting of 12 mmHg has no significant difference to 15 mmHg in the rate of postoperative complications, narcotic use, and intraoperative bleeding.

PURPOSE OF REVIEW: Recent advancements in the management of clinical stage II (CS II) testicular cancer have transformed it into a predominantly curable condition. This success in treatment advancements has markedly extended patient survival. However, these treatments carry risks and morbidities, which is important to consider given the disease's impact on young men and the emerging understanding of long-term treatment consequences. RECENT FINDINGS: Emerging data support primary retroperitoneal lymph node dissection (RPLND) for select CS II seminoma patients, with similar short-term outcomes to chemotherapy but less treatment intensity. Recent studies have also challenged the reflexive use of adjuvant chemotherapy for pathologic node-positive disease, as growing evidence shows low relapse rates regardless of nodal stage. Furthermore, novel biomarkers like circulating serum microRNA-371a-3p levels can help predict the presence of viable germ cell tumor at time of RPLND. SUMMARY: Advances in risk stratification and therapy enable personalized de-escalation approaches for oligometastatic testicular cancer, optimizing survivorship. Upfront RPLND, reassessing adjuvant systemic therapy for RPLND pN+ disease, and novel biomarkers will shape precision treatment to achieve high cure rates with excellent quality of life. Ongoing trials of reduced-intensity regimens, accurate prognostic models, improved surgical strategy, and emerging biomarkers represent the next frontier in tailored curative therapy.

BACKGROUND AND OBJECTIVES: We evaluated the unmet breast cancer-related lymphedema (BCRL) treatment and education needs at New England's largest safety-net hospital serving a diverse population by assessing prevalence, risk factors, and treatment. METHODS: This was a retrospective cohort study examining breast cancer surgery patients from September 2016 to September 2021. The primary outcome was BCRL diagnosis. Secondary outcomes included BCRL risk factors, and physical and occupational therapy (PT/OT) referral frequency and completion. RESULTS: Of 639 patients, 17% of patients had documented BCRL, which was significantly associated with axillary lymph node dissection (ALND). There were no racial, insurance, breast radiation, or BMI category differences between patients with and without a BCRL diagnosis. Of those with BCRL, 58% received a PT/OT referral, and 56% completed their referral. There were no racial, insurance, or BMI category differences between those who received a PT/OT referral and those who did not. CONCLUSION: In our high-risk population, rates of documented BCRL were higher than expected, approaching rates of ALND, despite the majority undergoing sentinel lymph node biopsy (SLNB). PT/OT referral and completion rates were low, concerning for an unmet BCRL treatment and education need. No disparities in care delivery were seen, but a program that addresses treatment gaps and ensures accessible and patient-centered BCRL care is urgently needed.

PURPOSE: Routine use of abdominal drain or prolonged antibiotic prophylaxis is no longer part of current clinical practice in colorectal surgery. Nevertheless, in patients undergoing laparoscopic right hemicolectomy with intracorporeal anastomosis (ICA), it may reduce perioperative abdominal contamination. Furthermore, in cancer patients, prolonged surgery with extensive dissection such as central vascular ligation and complete mesocolon excision with D3 lymphadenectomy (altogether radical right colectomy RRC) is called responsible for affecting postoperative ileus. The aim was to evaluate postoperative resumption of gastrointestinal functions in patients undergoing right hemicolectomy for cancer with ICA and standard D2 dissection or RRC, with or without abdominal drain and prolonged antibiotic prophylaxis. METHODS: Monocentric factorial parallel arm randomized pilot trial including all consecutive patients undergoing laparoscopic right hemicolectomy and ICA for cancer, in 20 months. Patients were randomized on a 1:1:1 ratio to receive abdominal drain, prolonged antibiotic prophylaxis or neither (I level), and 1:1 to receive RRC or D2 colectomy (II level). Patients were not blinded. The primary aim was the resumption of gastrointestinal functions (time to first gas and stool, time to tolerated fluids and food). Secondary aims were length of stay and complications' rate. CLINICALTRIALS: gov no. NCT04977882. RESULTS: Fifty-seven patients were screened; according to sample size, 36 were randomized, 12 for each arm for postoperative management, and 18 for each arm according to surgical techniques. A difference in time to solid diet favored the group without drain or antibiotic independently from standard or RRC. Furthermore, when patients were divided with respect to surgical technique and into matched cohorts, no differences were seen for primary and secondary outcomes. CONCLUSION: Abdominal drainage and prolonged antibiotic prophylaxis in patients undergoing right hemicolectomy for cancer with ICA seem to negatively affect the resumption of a solid diet after laparoscopic right hemicolectomy with ICA for cancer. RRC does not seem to influence gastrointestinal function recovery.

BACKGROUND: Pancreatic fistula (PF) is one of the most serious postoperative complications of gastrectomy. Misidentification of the boundary between the pancreas and the dissected fat is a primary concern. In this study, we focused on differences in the appearance of the pancreas and the dissected fat in actual surgical images and statistically analyzed the relationship between the pancreas and the dissected fat. METHODS: We analyzed data from 109 gastric cancer patients who underwent curative gastrectomy between November 2018 and March 2023. Intraoperative images were taken from videos of lymph node dissections of Nos.6 and 8a regions, and the mean gray value of the areas was measured using ImageJ software for analysis. The visceral fat area (VFA) was evaluated by preoperative axial CT at the umbilical level using Ziostation software. RESULTS: A significant correlation was observed between the fat/pancreas gray value ratio in the No.8a lymph node region and the drain/serum amylase ratio (P < 0.001). The fat/pancreas gray value ratio in the No.6 lymph node region correlated with VFA (P < 0.001). The VFA and drain/serum amylase ratio were significantly higher in the group with intra-abdominal complications (P = 0.004). CONCLUSIONS: We revealed significant relationships between the fat/pancreas gray value ratio with drain/serum amylase and VFA. Detecting differences in gray values between the pancreas and the dissected fat may lead to a decrease in the drain/serum amylase ratio and PF.

BACKGROUND: Axillary lymph node dissection (ALND) in breast cancer management, necessitates a nuanced understanding of complications that may impede treatment progression. This study scrutinize the impact of Haemoblock hemostatic solution, evaluation it's potential in reducing seroma complication by controlling lymph flow and obliterating axillary dead space. METHOD: A prospective, randomized, double-blinded controlled trial was conducted with 58 patients undergoing breast conserving surgery (BCS) and ALND, stratified into two groups: Group A (ALND + Haemoblock, n = 29) and Group B (ALND + placebo, n = 29). Postoperative drainage charts were monitored, with the primary endpoint being the time to drain removal, Additionally, patients were observed for surgical site infection (SSI). RESULTS: Group A exhibited a marginally higher mean total drain output (398 +/- 205 vs. 326 +/- 198) compared to Group B, this difference did not attain statistical significance (p = 0.176). Equally, the mean time to drain removal demonstrated no discernible distinction between the two groups (6 +/- 3.0 vs. 6 +/- 3.0, Group A vs. Group B, p = 0.526). During follow up, nine patients in Group A required seroma aspiration (mean aspiration 31 +/- 73) as compared to Group B, 6 patients required aspiration (mean aspiration 12 +/- 36), p = 0.222). No notable disparity in SSI rates between the groups was identified. CONCLUSION: In conclusion, the administration of Haemoblock did not manifest a discernible effect in mitigating seroma production, hastening drain removal, or influencing SSI rates following ALND. The study underscores the intricate and multifactorial nature of seroma formation, suggesting avenues for future research to explore combined interventions and protracted follow-up periods for a more comprehensive understanding.

BACKGROUND: Breast cancer-related lymphedema (BCRL) is a potentially disabling and often irreversible consequence of breast cancer treatment, caused by the mechanical incompetence of the lymphatic system, resulting in reduced drainage capacity and functional overload due to an excessive volume of interstitial fluid surpassing the system's transport capacity in the arm. We wanted to determine the impact and explore the differences in independent risk factors for the occurrence of BCRL; incidence of BCRL over a five-year period at the Institute of Oncology Vojvodina in Sremska Kamenica and to answer the research question regarding the influence of the prehabilitation program on the overall incidence of BCRL during the observed five-year period. METHODS: From 2014 to 2018, a retrospective study was conducted at the Institute of Oncology of Vojvodina in Sremska Kamenica, analyzing female patients who had undergone breast cancer surgery. RESULTS: The study included 150 breast cancer patients who developed secondary lymphedema following surgery with the mean age of 59.2 ± 11.3 years. Fluctuations in hospitalization rates were observed over the five-year period, with the highest number of admissions in 2014 (24.0%) and a decline in 2018 (14.0%). The most common surgical procedure performed was left quadrantectomy (24.0%), followed by right quadrantectomy (20.0%) and left amputation (15.3%). The mean number of removed lymph nodes was 15.2 ± 6.1, with no statistically significant association between the number of removed lymph nodes and the manifestation of secondary lymphedema. The severity of secondary lymphedema varied based on patient age, with a higher incidence of moderate and severe lymphedema observed in patients aged 61 years and older. Patients who underwent radical surgery were more likely to experience severe lymphedema compared to those who had conservative surgery, although this difference was not statistically significant. CONCLUSION: In our study, the type of surgery, elapsed time since surgery, and the number of removed lymph nodes were not influencing factors for the occurrence of BCRL. However, concerning its severity, a greater number of systemic therapy modalities combined with radiotherapy were associated with a more frequent occurrence of mild and moderate BCRL. Also, the severity of BCRL varied among different age groups, with a higher incidence of moderate and severe lymphedema observed in patients aged 61 years and older. Ultimately, improving the quality of life for individuals affected by secondary lymphedema remains a crucial goal in the field of oncology.
