Perspective on cytoreduction and metastasis-directed therapy in node positive and metastatic urothelial carcinoma of the bladder.

The outcome of node positive or metastatic urothelial carcinoma of the bladder (mUCB) is poor and palliative chemotherapy has long been considered the only treatment option for this patient group. Cytoreduction and metastasis-directed therapy, either by surgery or radiotherapy, has been successfully applied in other metastatic solid tumors in order to increase survival. In this article, we explore the literature supporting cytoreduction and metastasis-directed therapy in node positive and mUCB and try to define a patient cohort that could benefit from these treatments. From these data, it is clear that a selected group of patients survive a long time or could even be cured, however the data are scarce and the level of evidence is low. The criteria of a randomized clinical trial, to deliver the necessary evidence, are proposed.

Pulmonary Laser Metastasectomy by 1318-nm Neodymium-Doped Yttrium-Aluminum Garnet Laser: A Retrospective Study About Laser Metastasectomy of the Lung.

The lungs are among the first organ affected by remote metastases from many primary tumors. The surgical resection of isolated pulmonary metastases represents an important and effective element of therapy. This is a retrospective study about our entire experience with pulmonary resection for metastatic cancer using 1318-nm neodymium-doped yttrium-aluminum garnet laser.

Brain metastases epidemiology in a Tunisian population: trends and outcome.

Combined Hepatic and Pulmonary Metastasectomies From Colorectal Carcinoma. Data From the Prospective Spanish Registry 2008-2010.

Resection of both liver and lung metastases from colorectal carcinoma (CRC) is a standard of care in selected patients with oligometastatic disease. We present here the analysis of the subgroup of patients undergoing combined surgery from the Spanish Group of Surgery of Pulmonary Metastases (PM) from Colorectal Carcinoma (GECMP-CCR-SEPAR).

Managing Patients With Oligometastatic Non-Small-Cell Lung Cancer.

Metastatic lung cancer has long been considered incurable, with the goal of treatment being palliation. However, a clinically meaningful number of these patients with limited metastases (approximately 25%) are living long term after definitive treatment to all sites of active disease. These patients with so-called oligometastatic disease likely represent a distinct clinical group who may possess a more indolent biology compared with their more widely metastatic counterparts. Hellman and Weichselbaum proposed the existence of the oligometastatic state, on the basis of the spectrum theory of cancer spread. The literature suggests that an oligometastatic state exists in patients with non-small-cell lung cancer (NSCLC). This observation in the setting of rapidly evolving systemic therapies, including immune checkpoint inhibitors and an increasing number of targeted therapies, represents a unique clinical opportunity. Metastasis-directed therapies to address sites of disease include surgery (metastasectomy) and/or radiation therapy. Available evidence suggests that treating patients with limited or oligometastases may improve outcomes in a meaningful way; however, the majority of the randomized data includes patients with intracranial metastatic disease, and there are limited robust, randomized data available in the setting of NSCLC with only extracranial sites of metastatic disease. Ongoing randomized trials, including NRG-LU002 and the UK Conventional Care Versus Radioablation (Stereotactic Body Radiotherapy) for Extracranial Oligometastases trial, are aimed at evaluating this question further. One of the current limitations of aggressive treatment of oligometastatic NSCLC is the inability to accurately identify these patients before therapy, yet molecular markers, including microRNA profiles, are being investigated as a promising way to identify these patients.

Dosing oxaliplatin in a haemodialysis patient with metastatic rectum cancer monitored by free platinum concentrations.

Oxaliplatin in combination with fluorouracil and folinic acid is one of the preferred chemotherapeutic options in the treatment of metastatic rectum cancer. However, oxaliplatin is contraindicated in patients with a creatinine clearance <30 mL/min and dosing guidelines in patients on haemodialysis have not been established.

Utilization of targeted near-infrared molecular imaging to improve pulmonary metastasectomy of osteosarcomas.

Pulmonary metastasectomy for osteosarcoma provides a select group of patients an opportunity for long-term survival and possible cure. Unfortunately, a complete metastasectomy is challenging due an inability to accurately identify lesions that lay below the threshold of preoperative imaging or intraoperative visual and tactile inspection. Growing evidence suggests that osteosarcomas express a number of unique molecular markers, including the folate receptor alpha. In this case report, we describe the application of a folate receptor-targeted, near-infrared optical contrast agent (OTL38) to improve osteosarcoma localization during minimally invasive pulmonary resection. In addition to localizing preoperatively identified lesions, this technology helped identify additional disease that was undetected on preoperative imaging or with traditional intraoperative techniques. This report marks the first successful utilization of a molecular imaging probe useful for osteosarcomas. This technology may provide a unique approach to improve pulmonary metastasectomy of osteosarcomas.

A long-term survival case treated with conversion surgery following chemotherapy after diagnostic metastasectomy for pancreatic cancer with synchronous liver metastasis.

Pancreatic cancer with distant metastases is classified as "unresectable," for which the standard treatment is systemic chemotherapy. The effectiveness of radical resection for pancreatic cancer with distant metastases is unknown. Here, we report a case of long term survival treated with conversion surgery following chemotherapy after diagnostic metastasectomy for pancreatic cancer with synchronous liver metastasis.

Prognoses and Clinical Outcomes of Primary and Recurrent Uveal Melanoma.

Uveal melanoma has a very poor prognosis despite successful local primary tumor treatment. In this study, we investigated prognostic factors that more accurately reflected the likelihood of recurrence and survival and delineated a prognostic model that could effectively identify different risk groups based on initial clinical parameters.

Predictors for a further local in-brain progression after re-craniotomy of locally recurrent cerebral metastases.

Treatment of recurrent cerebral metastases is an emerging challenge due to the high local failure rate after surgery or radiosurgery and the improved prognosis of patients with malignancies. A total of 36 patients with 37 metastases who underwent surgery for a local in-brain progression of a cerebral metastasis after previous metastasectomy were retrospectively analyzed. Degree of surgical resection on an early postoperative MRI within 72 h after surgery was correlated with the local in-brain progression rate and overall survival. Complete surgical resection of locally recurrent cerebral metastases as confirmed by early postoperative MRI could only be achieved in 37.8%. Detection of residual tumor tissue on an early MRI following recurrent metastasis surgery correlated with further local in-brain progression when defining a significance level of p = 0.05 but not after Šidák or Bonferroni significance level correction for multiple testing: However, definite local tumor control could finally be achieved in 91.9% after adjuvant therapy. Overall survival after recurrent metastasectomy was significantly higher as predicted by diagnosis-specific graded prognostic assessment (12.9 ± 2.3 vs. 8.4 ± 0.7 months; p < 0.0001). However, our series involved a limited number of heterogeneous patients. A larger, prospective, and controlled study is required. Considering the adequate local tumor control achieved in the vast majority of patients, surgery of recurrent metastases may represent one option in a multi-modal treatment approach of patients suffering from locally recurrent cerebral metastases.

Mesenteric fibrosis and palliative surgery in small intestinal neuroendocrine tumours.

Mesenteric fibrosis (MF) surrounding a mesenteric mass is a hallmark feature of small intestinal neuroendocrine tumours (SI-NETs). Since this can induce intestinal obstruction, oedema and ischaemia, prophylactic resection of the primary tumour and mesenteric mass is often recommended. This study assessed predictors for mesenteric metastasis and fibrosis and the effect of MF and palliative surgery on survival. This study is a retrospective analysis of 559 patients with pathologically proven SI-NET and available CT-imaging data was performed. Clinical characteristics, presence of mesenteric mass and fibrosis on CT-imaging and the effect of palliative abdominal surgery on overall survival were assessed. We found that MF was present in 41.4%. Older age, 5-HIAA excretion ≥ 67 µmol/24 h, serum CgA ≥ 121,5 µg/l and a mesenteric mass ≥ 27.5 mm were independent predictors of MF. In patients ≤ 52 years, mesenteric mass was less often found in women than in men (39% vs 64%, p=0.002). Corrected for age, tumour grade, CgA and liver metastasis, MF was not a prognostic factor for overall survival. In patients undergoing palliative surgery, metastasectomy of mesenteric mass or prophylactic surgery did not result in survival benefit. We confirmed known predictors of MF and mesenteric mass and suggest a role for sex hormones as women ≤ 52 years have less often a mesenteric mass. Furthermore, the presence of MF has no effect on survival in a multivariate analysis and we found no benefit of metastasectomy of mesenteric mass or prophylactic surgery on overall survival.

Correction to: Metastasectomy for Tumor-Infiltrating Lymphocytes: An Emerging Operative Indication in Surgical Oncology.

In the original article the middle initial of Nicholas D. Klemen was inadvertently omitted. On the first page of the original article, under the heading A Novel Way to Fight Cancer, there was an error in the third sentence. The corrected text is as follows: For example, the presence of T cells within tumors of colorectal origin can be a superior predictor of patient survival compared with the standard histopathologic methods currently used to stage colorectal cancer.6,7.

Clinical Factors Predicting Better Survival Outcome for Pulmonary Metastasectomy of Hepatocellular Carcinoma.

In patients with lung metastasis of hepatocellular carcinoma (HCC), it remains uncertain how a better survival outcome can be predicted after metastasectomy. This study aims to identify clinical factors that may be used to guide patient selection for such a therapeutic modality. A total of 28 patients who received pulmonary metastasectomy for HCC between 1993 and 2012 were identified. All relevant clinical factors were extracted from medical records up to September 2015. Patients were classified into high- and low-risk groups according to survival outcome after metastasectomy. All pertinent clinical factors were analyzed for correlation with survival outcome.

The Benefit of a Surgical Resection of a Solitary Pulmonary Metastasis of Prostate Cancer after Radical Prostatectomy.

Historically, a solitary pulmonary metastasis of prostate cancer was considered as metastatic or disseminated disease and could only be treated systemically. However, some patients may benefit from surgical metastasectomy of a solitary pulmonary metastasis. We present an uncommon case of resection of a solitary pulmonary metastasis of prostate cancer after previous radical prostatectomy, resulting in un-detectable prostate specific antigen.

Primary Tumor Location and Survival in the General Population With Metastatic Colorectal Cancer.

Recent evidence from clinical trials suggests that primary tumor location in patients with metastatic colorectal cancer correlates with differential outcomes, and patients with tumors originating in the right side of the colon have inferior survival. We conducted a large population-based cohort study using individual patient data to confirm the prognostic importance of primary tumor location in the general population with metastatic colorectal cancer.

The Immunoscore system predicts prognosis after liver metastasectomy in colorectal cancer liver metastases.

The Immunoscore was initially established to evaluate the prognosis of stage I/II/III colorectal cancer patients. However, the feasibility of the Immunoscore for the prognosis of colorectal cancer liver metastases (CRCLM) has not been reported.

Metastasectomy for recurrent or metastatic biliary tract cancers: A single center experience.

To assess efficacy or long-term result of metastasectomy for recurrent or metastatic biliary tract carcinoma (BTC), we conducted a retrospective review of the outcomes of metastasectomy for recurrent or metastatic BTCs, comprising intrahepatic cholangiocellular carcinoma (IHCCC), proximal and distal common bile duct cancer (pCBDC and dCBDC), gallbladder cancer (GBC), and ampulla of Vater cancer (AoVC).

Is pulmonary metastasectomy beneficial in head and neck squamous cell carcinoma? A review of literature.

Metastatic head and neck squamous cell carcinoma (HNSCC) has traditionally carried a dismal prognosis; however with advances in care, it has been shown that pulmonary metastasectomy is a viable therapeutic option in selected patients, palliating symptoms and improving survival. With the increasing incidence of human papilloma virus-related HNSCC and better availability of minimal access surgery, there is a need to better understand the role of pulmonary metastasectomy in the treatment of HNSCC. This article summarizes the literature on indications, results, surgical options and approaches, clinical dilemmas, and controversies associated with pulmonary metastasectomy in HNSCC, to identify suitable candidates and optimize outcomes.

A multidisciplinary approach for the management of earlier stage renal cell carcinoma.

Transitioning agents that are effective in advanced disease to earlier disease settings is a common pathway for drug development and a concept that has been applied to multiple agents across several tumor types. This approach is relevant in high risk renal cell carcinoma (RCC) where the relapse rate is high. Unfortunately, between 20% and 40% relapse after nephrectomy and approximately one third of patients have evidence of metastasis at initial diagnosis. These patients will proceed with focal or systemic therapy during the course of disease.

Metastasectomy for Tumor-Infiltrating Lymphocytes: An Emerging Operative Indication in Surgical Oncology.

Adoptive cell transfer (ACT) of tumor-infiltrating lymphocytes (TILs) is an emerging immunotherapy for metastatic cancer. Surgeons play a central role in ACT treatments by performing resection of tumors from which TILs are isolated. It is important that surgeons have familiarity with this emerging treatment method because it is increasingly performed for an expanding variety of solid tumors at institutions around the world. This report offers a brief introduction to ACT for cancer, highlights historical milestones in its development, and provides patient selection and operative considerations for surgeons called upon to perform metastasectomy for the purpose of isolating TILs.

Prognostic value of site-specific metastases and therapeutic roles of surgery for patients with metastatic bladder cancer: a population-based study.

We aimed to evaluate the prognostic value of site-specific metastases in patients with metastatic bladder cancer and analyze the roles that surgeries play in the treatment of this malignancy.

Primary Upper Urinary Tract Small Cell Carcinoma: A Case Series and Literature Review.

Background: Primary upper urinary tract small cell carcinoma (SCC) is exceedingly rare with < 30 cases reported in the literature. Little is known about the incidence, diagnosis, treatment, and outcomes in these patients. We present a series of three patients with primary upper tract SCC. Case Presentation: Patient 1 is an 89-year-old Caucasian male who presented with hydroureteronephrosis and a mass in the proximal right ureter. Biopsy revealed SCC. Without further intervention, the patient died 2 months after his diagnosis. Patient 2 is a 67-year-old Caucasian female who underwent left laparoscopic nephroureterectomy for primary distal ureteral SCC, pT4N1M0. She developed lymphadenopathy and completed external beam radiation to the pelvis and four courses of cisplatin-based chemotherapy. She died from metastatic disease 7 months after diagnosis. Patient 3 is a 45-year-old female who underwent open right radical nephrectomy, retroperitoneal lymph node dissection, and hepatic metastasectomy for metastatic primary upper tract SCC, pT3N1M1. She underwent two subsequent retroperitoneal debulking procedures for recurrence followed by treatment with octreotide. She developed widespread metastasis and was treated with temozolomide and capecitabine before her death 80 months after diagnosis. Conclusion: This series contributes to the limited knowledge of the management and natural course of primary upper tract SCC. Patient 1 represents the first disease-specific mortality reported in a patient who received no therapy. Patient 3 represents the longest reported survival with metastatic disease, and the first treated with octreotide. The patient was managed with aggressive repeat surgical resection and exhibited 2 years of progression-free survival on octreotide. Emphasis should be placed on aggressive resection of all visible disease combined with the use of multimodal adjuvant chemoradiation for selected patients in this rare disease.

To evaluate our experience with metastasectomy following partial response or stable disease after treatment with high-dose interleukin-2 (HD IL-2).

Risk of leptomeningeal carcinomatosis in patients with brain metastases treated with stereotactic radiosurgery.

There is limited available literature examining factors that predispose patients to the development of LMC after stereotactic radiosurgery (SRS) for brain metastases. We sought to evaluate risk factors that may predispose patients to LMC after SRS treatment in this case-control study of patients with brain metastases who underwent single-fraction SRS between 2011 and 2016. Demographic and clinical information were collected retrospectively for 19 LMC cases and 30 controls out of 413 screened patients with brain metastases. Risk factors of interest were evaluated by univariate and multivariate logistic regression analyses and overall survival rates were evaluated by Kaplan-Meier survival analysis. About 5% of patients with brain metastases treated with SRS developed LMC. Patients with LMC (median 154 days, 95% CI 33-203 days) demonstrated a poorer overall survival than matched controls (median 417 days, 95% CI 121-512 days, p = 0.002). The most common primary tumor histologies  that lead to the development of LMC were non-small cell lung cancer (36.8%), breast cancer (26.3%), and melanoma (21.1%). No association was found between the risk of LMC and the location of the brain lesion or total volume of brain metastases. Prior surgical resection of brain metastases before SRS was associated with a 6.5 times higher odds (95% CI 1.45-29.35, p = 0.01) of developing LMC post-radiosurgery compared to those with no prior resections of brain metastases. Additionally, adjuvant WBRT may help to reduce the risk of LMC and can be considered in decision-making for patients who have had brain metastasectomy.
