Factors Associated With Upstaging of Melanoma Thickness on Final Excision.

Introduction: The incidence and risk factors associated with upstaging from initial biopsy to definitive excision in cutaneous melanoma have not been established. The aim of this study was to determine the incidence of tumor stage upstaging and associated risk factors using the National Cancer Database.

Methods: A retrospective study of the National Cancer Database between 2012 and 2016 was performed.

Integrating 31-Gene Expression Profiling With Clinicopathologic Features to Optimize Cutaneous Melanoma Sentinel Lymph Node Metastasis Prediction.

Unlabelled: National guidelines recommend sentinel lymph node biopsy (SLNB) be offered to patients with > 10% likelihood of sentinel lymph node (SLN) positivity. On the other hand, guidelines do not recommend SLNB for patients with T1a tumors without high-risk features who have < 5% likelihood of a positive SLN. However, the decision to perform SLNB is less certain for patients with higher-risk T1 melanomas in which a positive node is expected 5%-10% of the time.

Randomized controlled trial of the mySmartSkin web-based intervention to promote skin self-examination and sun protection behaviors among individuals diagnosed with melanoma: study design and baseline characteristics.

>1.2 million people in the United States have a personal history of melanoma skin cancer and are at increased risk for disease recurrence and second primary melanomas. Many of these individuals do not follow recommendations to conduct regular, thorough skin self-examinations that facilitate early disease detection and do not sufficiently engage in sun protection behaviors.

Malignant Melanoma in African-Americans: A Population-Based Clinical Outcomes Study Involving 1106 African-American Patients from the Surveillance, Epidemiology, and End Result (SEER) Database (1988-2011).

Malignant melanoma accounts for 75% of all skin cancer deaths and is potentially curable if identified early. Although melanoma is rare in African-Americans (AA), it is associated with a worse prognosis than in Caucasians. This study examines the demographic, pathologic, and clinical factors impacting AA melanoma outcomes.

Radiation Therapy is Associated with Improved Outcomes in Merkel Cell Carcinoma.

Background: Following wide excision of Merkel cell carcinoma (MCC), postoperative radiation therapy (RT) is typically recommended. Controversy remains as to whether RT can be avoided in selected cases, such as those with negative margins. Additionally, there is evidence that RT can influence survival.

Both tumor depth and diameter are predictive of sentinel lymph node status and survival in Merkel cell carcinoma.

Background: The purposes of this study were 1) to determine the impact of primary tumor-related factors on the prediction of the sentinel lymph node (SLN) status and 2) to identify clinical and pathologic factors associated with survival in Merkel cell carcinoma (MCC).

Methods: An institutional review board-approved, retrospective review of patients with MCC treated between 1988 and 2011 at a single center was performed. Patients were categorized into 5 groups: 1) negative SLN, 2) positive SLN, 3) clinically node-negative but SLN biopsy not performed, 4) regional nodal disease without a known primary tumor, and 5) primary MCC with synchronous clinically evident regional nodal disease.

Tumor infiltrating lymphocyte therapy for metastatic melanoma: analysis of tumors resected for TIL.

Adoptive cell transfer of tumor-infiltrating lymphocytes (TILs) can mediate objective tumor regression in 49% to 72% of patients with many long-term durable responses. To undergo treatment a patient must have (1) a resectable tumor from which (2) TIL can be generated that (3) exhibit tumor-specific reactivity. From July 2002 to July 2007, 787 tumors from 402 patients were processed for possible use in the generation of TIL, leading to the eventual treatment of 107 patients (27%).

Thoracic metastasectomy for adoptive immunotherapy of melanoma: a single-institution experience.

Objectives: Although refractory to chemotherapy, metastatic melanoma may respond to adoptive immunotherapy. As novel treatments evolve, surgeons may be asked to perform metastasectomy not only for palliation or potential cure but also for isolation of tumor-infiltrating lymphocytes. This study was undertaken to examine outcomes of patients with melanoma undergoing thoracic metastasectomy in preparation for investigational immunotherapy.

Impact of a recombinant fowlpox vaccine on the efficacy of adoptive cell therapy with tumor infiltrating lymphocytes in a patient with metastatic melanoma.

A patient with metastatic melanoma who had progressive disease after prior surgical resections, high dose interleukin-2, and anti-cytotoxic T lymphocyte antigen-4 antibody received sequential treatments with autologous tumor infiltrating lymphocytes that recognized the gp100 melanocyte differentiation antigen. Although no clinical response was seen when cells were administered alone, an objective clinical response to therapy was seen with tumor infiltrating lymphocytes administered together with a highly immunogenic fowlpox vaccine expressing a gp100: 209-217 (210M) epitope. Persistence of the transferred antigen-specific lymphocytes in the peripheral blood was observed only after adoptive cell therapy plus administration of vaccine.

Single-pass, closed-system rapid expansion of lymphocyte cultures for adoptive cell therapy.

Adoptive cell therapy (ACT) for metastatic melanoma involves the ex vivo expansion and reinfusion of tumor infiltrating lymphocytes (TIL) obtained from resected specimens. With an overall objective response rate of 56%, this T-cell immunotherapy provides an appealing alternative to other therapies, including conventional therapies with lower response rates. However, there are significant regulatory and logistical concerns associated with the ex vivo activation and large-scale expansion of these cells.

Adoptive cell therapy for patients with metastatic melanoma: evaluation of intensive myeloablative chemoradiation preparative regimens.

Purpose: The two approved treatments for patients with metastatic melanoma, interleukin (IL)-2 and dacarbazine, mediate objective response rates of 12% to 15%. We previously reported that adoptive cell therapy (ACT) with autologous antitumor lymphocytes in lymphodepleted hosts mediated objective responses in 51% of 35 patients. Here, we update that study and evaluate the safety and efficacy of two increased-intensity myeloablative lymphodepleting regimens.

Treatment of metastatic melanoma using interleukin-2 alone or in conjunction with vaccines.

Purpose: To identify prognostic factors associated with survival beyond 4 years and overall response in patients with metastatic melanoma treated with high-dose bolus i.v. interleukin-2 (IL-2) given either alone or in combination with a variety of melanoma vaccines.

High-dose interleukin-2 for the treatment of metastatic renal cell carcinoma : a retrospective analysis of response and survival in patients treated in the surgery branch at the National Cancer Institute between 1986 and 2006.

Background: The treatment of metastatic renal cell carcinoma (RCC) with high-dose interleukin-2 (HD IL-2) has resulted in durable tumor regression in a minority of patients. The current study presents the authors' 20-year experience administering this immunotherapeutic agent.

Methods: Patients with metastatic RCC (n = 259) were treated with HD IL-2 alone from January 13, 1986 through December 31, 2006 at the Surgery Branch of the National Cancer Institute.

Prognostic factors related to clinical response in patients with metastatic melanoma treated by CTL-associated antigen-4 blockade.

Purpose: CTL-associated antigen 4 (CTLA-4) can inhibit T-cell activation and helps maintain peripheral self-tolerance. Previously, we showed immune-related adverse events (IRAE) and objective, durable clinical responses in patients with metastatic melanoma treated with CTLA-4 blockade. We have now treated 139 patients in two trials and have sufficient follow-up to examine factors associated with clinical response.
