Multi-institutional analysis of stereotactic body radiotherapy for sarcoma pulmonary metastases: High rates of local control with favorable toxicity.

BACKGROUND/OBJECTIVES: Oligometastatic sarcoma pulmonary metastases (PM's) are traditionally treated with resection and/or chemotherapy. We hypothesize that stereotactic body radiotherapy (SBRT) is an effective, safe alternative to surgery that can achieve excellent local control (LC) with a favorable toxicity profile. METHODS: Patients treated with SBRT for sarcoma PM's from 2011 to 2016 at Massachusetts General Hospital and the University of Pennsylvania were included. Median dose was 50 Gy. Patients underwent computed tomography (CT) or positron emission tomography/CT Q3 months post-SBRT. RESULTS: 44 patients with 56 separate PM's were treated with SBRT. Median age was 59 (range 19-82). 82% received prior chemotherapy, 66% had prior pulmonary resections (range, 1-5 resections), and 32% received prior thoracic radiotherapy. Median lesion size was 2.0 cm (range, 0.5-8.1 cm). Median follow-up was 16 months and 25 months for patients alive at last follow-up. Overall survival at 12 and 24 months was 74% (95% confidence interval [CI], 67%-81%) and 46% (95% CI, 38%-55%). LC at 12 and 24 months was 96% (95% CI, 93%-98%) and 90% (95% CI, 84%-96%). LC and overall survival did not differ based on age, gender, histology, fractionation, lesion location, or size (P > .05). Three developed Common Terminology Criteria for Adverse Events version 4 grade-2 chest-wall toxicities; one had grade-2 pneumonitis. CONCLUSIONS: In the first multi-institutional series on SBRT for sarcoma PM's, SBRT has excellent LC and is well-tolerated. SBRT should be considered as an alternative/complement to resection.

Redefining the Role of Surgical Management of Metastatic Renal Cell Carcinoma.

PURPOSE OF REVIEW: The treatment landscape for metastatic renal cell carcinoma (mRCC) continues to evolve with ongoing advancements in systemic therapy, raising further questions about the optimal role of surgery in the management of mRCC. Herein, we provide a context and review of the recent evidence concerning the role of surgical therapy for patients with mRCC including cytoreductive nephrectomy and distant metastatectomy. RECENT FINDINGS: One randomized trial has been published in the targeted therapy era suggesting that initial systemic therapy is non-inferior to cytoreductive nephrectomy among patients with intermediate and poor-risk mRCC. Delaying cytoreductive nephrectomy until after systemic therapy may be a viable treatment approach, although a high level of evidence is lacking. Additional questions remain regarding the sequence of surgery with systemic therapy, utility of distant metastatectomy, as well as the application of these findings to the current generation of immunotherapy. Recent evidence challenges the need of upfront cytoreductive nephrectomy for unselected patients with mRCC. However, surgical therapy continues to play an important role in the management of the disease.

Efficacy and safety of stereotactic body radiation therapy for the treatment of pulmonary metastases from sarcoma: A potential alternative to resection.

BACKGROUND/OBJECTIVES: Oligometastatic sarcoma pulmonary metastases (PM) are typically treated with resection and/or chemotherapy. We hypothesize that stereotactic body radiotherapy (SBRT) can be an alternative to surgery that can achieve high rates of local control (LC) with limited toxicity. METHODS: Thirty consecutive sarcoma patients received SBRT to 39 PM's from 2011 to 2015 at two university hospitals to a median dose of 50 Gy in 4-5 fractions with CyberKnife or linear accelerator. Patients underwent CT or PET/CT scans q3 months after SBRT. RESULTS: 77% received prior chemotherapy, 70% had 1-3 prior pulmonary resections, and 26% received prior thoracic radiotherapy. Median lesion size was 2.4 cm (range 0.5-8.1 cm). Median follow-up was 16 and 23 months for patients alive at last follow-up. At 12 and 24 months, LC was 94% and 86%, and OS was 76% and 43%. LC and OS did not differ by SBRT technique, fractionation regimen, lesion location, histology, or size (all P > 0.05). Three developed grade 2 chest-wall toxicity with no other grade ≥2 toxicities. CONCLUSIONS: This is the largest series on SBRT for sarcoma PM's and demonstrates that SBRT is well-tolerated with excellent LC across tumor locations and sizes. SBRT should be considered in these patients, and prospective studies are warranted. J. Surg. Oncol. 2016;114:65-69. © 2016 Wiley Periodicals, Inc.

The role of local ablative therapy in oligometastatic non-small-cell lung cancer: hype or hope.

In recent years, the emergence of the oligometastatic state has called into question whether patients found to have a limited or low metastatic tumor burden may benefit from locally ablative therapy (LAT). In the past two decades, stereotactic body radiation therapy has been increasingly used to safely deliver LAT and provide high local control in nonoperable non-small-cell lung cancer patients. Mostly retrospective analyses suggest that using LAT for oligometastatic disease in non-small-cell lung cancer offers excellent local control and may provide an improvement in progression-free survival. Any meaningful improvement in cancer-specific survival remains debatable. We examine the role of integrating LAT in this patient population and the rationale behind its use in combination with targeted therapy and immunotherapy.

Multicenter retrospective analysis of metastatic colorectal cancer (CRC) with high-level microsatellite instability (MSI-H).

BACKGROUND: The microsatellite instability-high (MSI-H) phenotype, present in 15% of early colorectal cancer (CRC), confers good prognosis. MSI-H metastatic CRC is rare and its impact on outcomes is unknown. We describe survival outcomes and the impact of chemotherapy, metastatectomy, and BRAF V600E mutation status in the largest reported cohort of MSI-H metastatic colorectal cancer (CRC). PATIENTS AND METHODS: A retrospective review of 55 MSI-H metastatic CRC patients from two institutions, Royal Melbourne Hospital (Australia) and The University of Texas MD Anderson Cancer Center (United States), was conducted. Statistical analyses utilized Kaplan-Meier method, Log-rank test, and Cox proportional hazards models. RESULTS: Median age was 67 years (20-90), 58% had poor differentiation, and 45% had stage IV disease at presentation. Median overall survival (OS) from metastatic disease was 15.4 months. Thirteen patients underwent R0/R1 metastatectomies, with median OS from metastatectomy 33.8 months. Thirty-one patients received first-line systemic chemotherapy for metastatic disease with median OS from the start of chemotherapy 11.5 months. No statistically significant difference in progression-free survival or OS was seen between fluoropyrimidine, oxaliplatin, or irinotecan based chemotherapy. BRAF V600E mutation was present in 14 of 47 patients (30%). BRAF V600E patients demonstrated significantly worse median OS; 10.1 versus 17.3 months, P = 0.03. In multivariate analyses, BRAF V600E mutants had worse OS (HR 4.04; P = 0.005), while patients undergoing metastatectomy (HR 0.11; P = <0.001) and patients who initially presented as stage IV disease had improved OS (HR 0.27; P = 0.003). CONCLUSIONS: Patients with MSI-H metastatic CRC do not appear to have improved outcomes. BRAF V600E mutation is a poor prognostic factor in MSI-H metastatic CRC.

Outcomes of Robotic Surgery in a Single-institution, High-volume Hepatobiliary Oncology Unit.

Hepatobiliary surgery has traditionally been performed via an open approach. With the advent of robotic surgery, the minimal access approach in hepatobiliary oncology has gained impetus due to its technical superiority and favorable learning curve over laparoscopy. We present our experience with the Da Vinci Xi system in hepatobiliary oncology. This is a retrospective study from a prospectively maintained database. All patients who underwent surgery between June 2015 and July 2023 for suspected gallbladder cancer and primary or metastatic liver tumors were included. After excluding all inoperables and conversions, a total of 92 patients were included for analysis. There was a conversion rate of 15.6% (17 of 109 patients). Sixty-four (69.6%) patients underwent surgery for gallbladder-related pathologies that included 39 (60.9%) radical cholecystectomies, 24 (37.5%) simple cholecystectomies, and 1 (0.01%) revision cholecystectomy. Twenty-eight patients underwent surgeries for primary or metastatic liver tumors, which included 25 (92.9%) minor and 2 (7.1%) major hepatectomies. Significant morbidity (Clavien-Dindo grade III or more) was seen in 8 (8.6%). There was no postoperative mortality. In the group with gallbladder cancer, the median lymph nodal yield was 7 (2-22) in patients who underwent lymph nodal dissection. The median follow-up was 63.9 (0.49-100.67) (IQR = 37.76) months. The 5-year OS and DFS were 76.4 and 71.3%, respectively. Robotic hepatobiliary surgery is feasible and can be performed safely after adequate training. Patient selection is of utmost importance and is the key to establishing a robust robotic hepatobiliary oncosurgery program.

The Role of Surgery for Stage IV Melanoma.

Historically, stage IV melanoma carried a dismal prognosis and surgical resection was the only potential treatment offering long-term survival or palliation of symptomatic disease. With modern systemic therapies that can provide durable disease control for many patients with metastatic disease, we are actively redefining the role of surgery in metastatic melanoma. Contemporary treatment strategies can employ surgical resection in the upfront setting followed by adjuvant therapy, or used in tailored approach following systemic therapy. The combination of surgical resection and modern therapies has been associated with good long-term survival.

Palliative Surgery and Potential Curative Trajectory in a Nasopharyngeal Cancer Survivor With Isolated Lung Metastasis.

The role of palliative surgery for excision of metastasis in a patient with nasopharyngeal carcinoma (NPC) is limited. However, judicious patient selection can yield noteworthy long-term survival outcomes. We report a case of the occurrence of isolated lung metastasis and its management in a NPC survivor with a long disease-free interval. The patient underwent radiotherapy and chemotherapy in 2014 for primary NPC cT2N1M0. In November 2019, he presented with a cough and respiratory distress. The investigation unveiled an isolated lung metastasis that partially encased the left upper lobe bronchus and closely abutted the left main bronchus and left pulmonary artery. Following comprehensive multidisciplinary consultations involving the patient and relatives, the patient underwent a left pneumonectomy as an imperative palliative intervention to alleviate the symptomatic respiratory distress and long-term disease control. Remarkably, the patient's disease-free status has persisted post surgery until 2024, evoking consideration of a potential curative trajectory. This case emphasises comprehensive evaluations, multidisciplinary discussions, and individualised treatment plans. It encourages patients to remain optimistic and engaged in their healthcare journey.

Hepatic resection for metastatic melanoma in the era of targeted therapy: A case report.

INTRODUCTION: While prognosis in metastatic melanoma has traditionally been poor, novel systemic therapies such as immunotherapy and targeted agents have improved overall survival (Steininger et al., 2021). These medications are generally well tolerated but can be associated with immune related adverse events (Remash et al., 2021). Hepatic metastatectomy is an important component of management, conferring a survival benefit over systemic therapy alone in appropriately selected patients (Medina et al., 2020). Gadoxetic acid-enhanced magnetic resonance imaging (GA-MRI) has been demonstrated to have enhanced diagnostic accuracy compared with other imaging modalities for hepatic metastases (Freitas et al., 2021). The risk of tumour seeding associated fine-needle aspiration biopsy (FNAB) of hepatic lesions varies, with most studies reporting a low incidence (Maturen et al., 2006). PRESENTATION OF CASE: In February 2020, a 75-year-old male underwent wide local excision and sentinel lymph node biopsy for stage IIA (T2B, N0, M0) melanoma. Routine surveillance without adjuvant systemic treatment was commenced. In July 2022, he presented with haemoptysis and was subsequently diagnosed with widespread metastatic disease on positive emission tomography (PET). After combination ipilimumab and nivolumab, PET scans in August 2023 revealed new liver lesions with disease response at all other metastatic sites. Following a multi-disciplinary team (MDT) discussion, the patient proceeded to hepatic metastatectomy. Histopathology demonstrated chronic necrotising granulomatous hepatitis. DISCUSSION: This case reflects the challenges involved in investigation and management of hepatic metastases in melanoma. CONCLUSION: Despite the accuracy of modern imaging, this case demonstrates the need for MDT consideration of liver biopsy in patients on anti-CTL4 treatment or with response to systemic treatment at extrahepatic sites.

Surgical indication and management of obstructive colonic metastasis from primary lung adenocarcinoma: report of a case and review of the literature.

BACKGROUND: Colonic metastasis from lung cancer is very rare and is typically associated with poor prognosis. Herein, we report the case of a patient who achieved intermediate-term survival using a multimodal treatment approach, including chemotherapy, immunotherapy, radiotherapy, and surgical resection for obstructive colonic metastasis from primary lung adenocarcinoma. CASE PRESENTATION: A woman in her 50s presented with anemia and a positive fecal occult blood test. Computed tomography revealed a tumor in the right upper lobe of the lung with mediastinal lymphadenopathy and wall thickening in the transverse colon. Colonoscopy revealed a stricture involving 50% of the colonic lumen. Biopsy revealed a poorly differentiated adenocarcinoma positive for CK-7 and TTF-1, very focally positive for napsin A, and negative for CK-20 and CDX-2. Furthermore, positron emission tomography/CT (PET/CT) showed a high maximum standardized uptake value (SUVmax) of 8.2 in the iliac bone. Based on these findings, the patient was diagnosed with primary lung adenocarcinoma with simultaneous metastasis to the transverse colon and iliac bone (cT4N3M1c, cStage IVB). After receiving first-line chemotherapy with atezolizumab, pemetrexed, and carboplatin, the tumors shrank after 4 courses. Subsequently, the patient received maintenance therapy with atezolizumab and pemetrexed. However, the tumor enlarged after 10 courses. Second-line chemotherapy with docetaxel and ramucirumab (3 courses) failed to achieve tumor reduction. Colonoscopy revealed an impassable colonic tumor. Nineteen months after diagnosis, surgery was planned for imminent intestinal obstruction. We determined that the colonic tumor was resectable, because laparoscopic exploration revealed no other metastases. The tumor was resected by partial colectomy with ileocolonic anastomosis. The postoperative course was uneventful. Pathological examination revealed a resection margin that was negative for malignancy, and the histological type was consistent with metastatic lung adenocarcinoma. The patient then received nab-paclitaxel therapy; however, she developed symptoms of superior vena cava syndrome after 3 courses. The patient received palliative irradiation (30 Gy/10 fr) followed by nivolumab. She soon developed a solitary brain metastasis, and stereotactic irradiation was planned. After 3 courses of nivolumab, the metastasis was reduced significantly, and stereotactic brain irradiation was canceled. The lung tumor and mediastinal lymphadenopathy gradually shrank, and the patient survived for 13 months after surgery without disease progression. CONCLUSIONS: In this case, surgical resection of colonic metastasis from primary lung adenocarcinoma may have contributed to the short-term prognosis as a bridge-to-next available multimodal treatment.

Pulmonary metastatectomy in pediatric cancer patients at National Cancer Institute, Egypt: prognostic factors and outcome.

BACKGROUND: Metastatic tumors account for 80% of all lung tumors in children. Wilms tumour and osteosarcoma are the most tumors of childhood that produce lung metastases. The aim of the current study is to assess the prognostic factors of pulmonary metastatectomy in pediatric solid tumours as age, number, size, site,laterality, resectability of pulmonary nodules, and number of Thoracotomies. Calculate overall survival among patients who underwent pulmonary metastatectomy. METHODS: It is a retrospective study including all pediatric patients with metastatic solid tumors to lungs treated at pediatric oncology department, National Cancer Institute, Cairo University from 2008 to 2014. Fifty-five patients were included, 43 (78.2℅) patients of them had Osteosarcoma. RESULTS: Thirty (54.5℅)patients were male. The mean age was 15 years ranging from (4.5- 23) years. The site of primary disease was at lower limbs in 43 (78.2%) patients. All patients underwent complete surgical resection of the primary disease with negative margin, 22(51.1%) of the osteosarcoma patients did amputation with tumor necrosis less than 90%. All patients received chemotherapy and only 9 received radiation therapy. The patients were classified into four groups according to time of diagnosis of pulmonary metastasis: at time of diagnosis in 13 (21.8%) patients, within treatment in 16 (30.9%) patients, within first year follow up in 18 (32.7%) patients and detected late in 8 (14.5%) patients. Bilateral lung metastasis diagnosed by CT chest were detected in 42 (76.4%) patients. Size of metastatic nodules was ranging from (0.5 to 10 cm) with mean 3.4 cm. Number of metastatic nodules was ranging from (1 to 28) median 4.Metastatic complications were detected in 19 patients. 5-year OS was 74.8% in the study group, and 68% in osteosarcoma patients. Effect of prognostic factors as sex, time of respectability, laterality, tumor necrosis of the 1ry disease, Timing of lung metastasis, size and site of the primary, Surgical approach of metastatectomy, postoperative complications on overall survival of the studied patients was done with significant P-value of tumor necrosis of the 1ry disease and Timing of lung metastasis 0.017, 0.001 respectively. CONCLUSION: Resection of pulmonary metastases of pediatric solid tumours is a safe and effective treatment that offers better survival.

Surgical Management of Gestational Trophoblastic Neoplasia.

Gestational trophoblastic neoplasia (GTN) is primarily treated with chemotherapy, but surgery plays a key role at different steps in disease management, including initial diagnosis, primary therapy, and salvage options. Initial diagnosis is usually made by electric or manual vacuum aspiration for molar pregancy or uterine curettage for other forms of GTN. Excisional procedures of localized disease, whether second curettage or hysterectomy, can obviate chemotherapy, but patients still require monitoring for relapse. Resection remains a useful adjunct for either the management of isolated foci of chemoresistant disease or the management of bleeding complications.

Hepatectomy or/with Metastatectomy for Recurrent Intrahepatic Cholangiocarcinoma: Of Promise for Selected Patients.

Introduction: Intrahepatic cholangiocarcinoma (ICC) has devastating outcomes owing to its advanced stage at diagnosis and high recurrence after hepatectomy. There is no preferred treatment for recurrent ICC. We retrospectively reviewed our patients who underwent repeated operations for recurrent ICCs based on their different indications to appraise the outcomes. Methods: In all, 160 out of 216 patients with ICC (71.4%) experienced recurrence after curative resection from 1977 to 2014. The patterns of recurrence were categorized according to the locations and numbers of recurrent tumors. Results: Patients with merely intrahepatic recurrence (n = 38) had superior overall survival (OS) compared with those with beyond intrahepatic recurrence (p < 0.0001). Twenty-seven out of 160 patients (16.8%) underwent repeat hepatectomy or/with metastatectomy for recurrence and had superior OS when compared to the remaining 133 patients who received nonoperative treatment/palliation (85.6 months versus 20.9 months, p < 0.001). Furthermore, patients suitable for repeat hepatectomy in the intrahepatic recurrent group (n = 12) had superior post-recurrence overall survival (PROS) than the remaining 26 patients receiving nonoperative treatment (61.6 months versus 14.7 months, p < 0.05). Conclusion: Liver is the most commonly involved site of recurrent ICC. However, merely intrahepatic recurrence may have a favorable prognosis compared to recurrence involving other sites. Aggressive hepatectomy may provide a survival benefit in selected patients.

Can Surgical Resection of Metastatic Lesions Be Beneficial to Pancreatic Ductal Adenocarcinoma Patients with Isolated Lung Metastasis?

In the era of effective chemotherapy on pancreatic ductal adenocarcinoma (PDAC) with distant metastasis, data on the effects of metastatectomy are lacking. So, we investigated the effect of metastatectomy on survival after metastasis in PDAC patients with isolated lung metastasis. This retrospective study analyzed 1342 patients who were histologically diagnosed with PDAC with distant metastasis from January 2007 to December 2018, of which 83 patients had isolated pulmonary metastasis. Additionally, 4263 patients were extracted from the National Cancer Database (NCDB) and analyzed. Log-rank test and Kaplan−Meier survival analysis were used to analyze survival after metastasis. The five-year survival rate was significantly higher in patients who underwent pulmonary metastatectomy than in those who received only chemotherapy or supportive treatment (60.6% vs. 6.2% vs. 0.0%, p < 0.001). A similar trend was observed in the NCDB (two-year survival rate, 27.4% vs. 15.8% vs. 4.7%, p < 0.001). In the multivariate analysis, lung lesion multiplicity (hazard ratio (HR) = 2.004, p = 0.017), metastatectomy (HR = 0.278, p = 0.036), chemotherapy (HR = 0.434, p = 0.024), and chemotherapy cycles (HR = 0.300, p < 0.001) had significant effects on survival. Metastatectomy with primary pancreatic lesions is recommended with effective chemotherapy in PDAC patients with isolated lung metastasis.

Exploring an Unfathomed Entiry: A Pooled Analysis of Solitory Skeletal Muscle Metastasis from Head and Neck Squamous Cell Carcinoma.

Background: Skeletal muscle is relatively uncommon site for metastasis in head and neck primary. This study was conducted to report our experience of three such cases and analyze the previously reported cases to assess the overall outcomes and formulate a treatment plan for these patients. Methods: We pooled the data extracted on extensive literature review and analyzed. Results: A total of 17 patients were analyzed for this study. All the patients had locally advanced primary and 14/17 developed metachronous metastasis. Median duration to development of metastasis was 8.5 months, and 13/17 patients had skeletal muscle as the only site of metastasis. Only 6/13 were treated with aggressive intent, 4 of which who underwent surgical resection had the best survival outcomes. Conclusions: Isolated skeletal muscle metastasis in a head and neck primary is relatively rare, and in future, the research work needs to be taken up afresh, on prospective model, with adequate patient sample, to draw a scientifically valid conclusion.

Image-guided combined ablation and resection in thoracic surgery for the treatment of multiple pulmonary metastases: A preliminary case series.

OBJECTIVES: To demonstrate the feasibility and preliminary outcomes of a novel hybrid technique combining percutaneous microwave ablation and wire-assisted wedge resection for patients with multiple pulmonary metastases using intraoperative imaging. METHODS: We describe our technique and present a retrospective case series of 4 patients undergoing iCART at our institution between August 2018 and January 2020. Procedures were performed in a hybrid operating suite using the ARTIS Pheno cone beam computerized tomography scanner (Siemens Healthineers, Erlangen, German). Patient information included past history of malignancy as well as lesion size, depth, location, and histology result. Surgical complications and length of stay were also recorded. RESULTS: Five procedures were performed on 4 patients during the study period. One patient underwent bilateral procedures 4 weeks apart. All patients underwent at least 1 ablation and 1 wedge resection during the combined procedure. Patient ages ranged from 40 to 66 years and the majority (75%) were men. All had a past history of cancer. Lesions were treated in every lobe. Size and depth ranged from 6 to 24 mm and 21 to 33 mm, respectively, for ablated nodules and 5 to 27 mm and 0 to 22 mm, respectively, for the wedge resected nodules. Three procedures were completed uniportal and operative time ranged from 51 to 210 minutes. All cases sustained <10 mL blood loss. There were 2 intraoperative pneumothorax, 1 prevented successful completion of the ablation. One patient required a prolonged period of postoperative physiotherapy and was discharged on day 6. The other patients were discharged on postoperative day 2 or 3. All 5 histology specimens confirmed metastatic disease. CONCLUSIONS: Our hybrid approach provides a minimally invasive and comprehensive personalized therapy for patients with multiple pulmonary metastases under a single general anesthetic. It provides histology-based diagnosis whilst minimizing lung tissue loss and eliminating the need for transfer from radiology to operating theatre. Emergence of ablation as a treatment for stage 1 non-small cell lung cancer and the expansion of lung cancer screening may widen the application of iCART in the future.

Impact of Ovarian Metastatectomy on Survival Outcome of Colorectal Cancer Patients with Ovarian Metastasis: A Retrospective Study.

BACKGROUND: Ovarian metastasis from colorectal cancer (CRC) is rare and lacks standard treatment. The benefit of metastatectomy remains to be elucidated. This study was conducted to assess the impact of metastatectomy on survival outcome and explore prognostic factors in ovarian metastatic CRC patients. METHODS: Information of ovarian metastatic CRC patients between January 2008 and December 2017 were collected retrospectively from database of West China Hospital, Sichuan University. Kaplan-Meier method was used to estimate disease-specific survival (DSS) after diagnosis of ovarian metastasis, and multivariate Cox regression analysis was applied to identify prognostic factors. RESULTS: Totally, 68 female patients from a cohort of 2170 cases were eligible. The median age at diagnosis was 46.5 years. The median DSS was 25.0 months (95% confidence interval (CI): 21.0-29.0 months). Kaplan-Meier analysis and Log rank test showed that complete resection of ovarian metastases (median DSS: 33.0 months) could significantly prolong patients' survival time, compared with palliative and no resection (median DSS: 20.0 months and 22.0 months, respectively), regardless of systemic chemotherapy (P<0.05). Multivariate analysis demonstrated regional lymph nodes metastasis of primary tumor (hazard ratio (HR): 3.438, 95% CI: 1.094-10.810, P=0.035), primary tumor resection (HR: 6.436, 95% CI: 1.770-23.399, P=0.005), differentiation grade (HR: 0.272, 95% CI: 0.107-0.693, P=0.006), complete resection of ovarian metastases (vs palliative resection: HR: 17.091, 95% CI: 3.040-96.099, P=0.001; vs no resection: HR: 9.519, 95% CI: 1.581-57.320, P=0.014), and systemic chemotherapy (HR: 3.059, 95% CI: 1.089-8.595 P=0.034) were independent prognostic factors. CONCLUSION: Complete resection of ovarian metastases could independently predict favorable survival in ovarian metastatic CRC, while palliative resection could not improve patients' prognosis compared with no resection.

Solitary recurrence at intercostal drain site in oesophageal adenocarcinoma.

56 year old gentleman was evaluated for dysphagia and diagnosed with oesophageal adenocarcinoma and had undergone Transhiatal Oesophagectomy elsewhere, pT3N0, but had defaulted adjuvant treatment. He presented 15 months later to us with nodule at left intercostal drain (ICD) drain site. Positron Emission Tomography (PET) scan showed it to be single site metastasis and he underwent wide excision, followed by six cycles of chemotherapy. He is symptom free and on regular follow up for a period of ten months. Oesophageal cancer although with poor prognosis can be considered for metastatectomy after considering the disease free interval, site of recurrence and histological factors in carefully selected patient.

Brain Oligometastasis from Synchronous Uterine Malignancies.

Synchronous tumors of female genital tract have been uncommonly reported in literature. The most likely scenario would represent a metastatic disease from a primary tumor within the genital tract as the presence of primary synchronous tumors of the genital tract is an extremely rare event. Most primary synchronous tumors tend to involve the endometrium and ovary, while the incidence of synchronous primary tumors involving the uterine cervix and endometrium as documented in a few case series has been around 0.4%. We present a 41-year-old lady with an extremely rare occurrence of synchronous tumors of the uterus with an endometrioid adenocarcinoma of the uterine fundus and a squamous cell carcinoma of the uterine cervix. The patient presented to us with cerebral metastasis, which was successfully managed surgically.

Liver-first approach to stage IV colon cancer with synchronous isolated liver metastases.

BACKGROUND: The only possibility for cure in patients with colon adenocarcinoma (CAC) with isolated liver metastases (ILM) is resection of both primary and metastatic tumors. Little is known about the implication of the sequence in which a colectomy and hepatectomy are performed on outcomes. This study analyzes whether resection sequence impacts clinical outcomes. METHODS: The National Cancer Database was queried for CAC cases with hepatic metastases from 2010-2015 with exclusion of extrahepatic metastases. We compared patients treated with a liver-first approach (LFA) to those treated with a colectomy-first or simultaneous approach using Kaplan Meier and multivariable Cox proportional hazards analysis. RESULTS: In 21,788 CAC patients identified, the LFA was uncommon (2%), but was associated with higher rates of completion resection of remaining tumor (41% vs. 22%, P<0.001). Patients selected for LFA were younger, less comorbid, and more commonly received upfront chemotherapy (P<0.05). The LFA was associated with increased median survival [34 months, 95% CI (30.5-39.6 months) vs. 24 months, 95% CI (23.7-24.6 months), logrank P<0.001] and decreased risk of death [HR 0.783; 95% CI (0.67-0.89), P=0.001]. CONCLUSIONS: The LFA to CAC with synchronous ILM is uncommon but is associated with greater likelihood of receiving chemotherapy prior to surgery and increased survival in selected candidates.
