    Kurzfassung: e22005 Background: TIL include antigen specific clonal T cells responding to tumor antigens (TA) in the tumor microenvironment. Biological relevance of TIL at the PCM following ICI treatment of MM is not clear. Since there is overlap of TA between primary and its metastasis, we hypothesized that TIL at PCM site may serve as a biomarker of response to ICI treatment of MM. Methods: We did a retrospective analysis of MM patients (pts.) receiving ICI treatment between 2012 and 2019 following an IRB approved protocol. Response and survival at 12, 24 and 36 months (mths) was correlated with PCM site TIL. Pts. who received at least one dose of ICI for MM were eligible and those with metastasis from unknown PCM, received anti-BRAF treatment or lacked information on TIL at PCM were excluded. Pts. were stratified as group (gr.) A, B and C representing brisk, non-brisk and absent TIL respectively. Responses defined by RECIST criteria (response, no response, stable disease) as well as overall survival calculated from time of initiation of ICI to death from any cause (OS) at 12, 24 and 36 mths was correlated to TIL at PCM. Results: 42 pts. received ICI for MM between 2012-2019 meeting the eligibility criteria. Median age is 68 years (yrs.) (63, 71 and 73 yr. respectively for group A, B and C), 27 male, 15 women. The median thickness of PCM was 3.5, 3.75 and 4.75 mm in group A, B and C respectively. 11 of 14, 9 of 16 and O of 12 pts. responded to ICI while 2, 5, 14 and 1,2, 0 patients showed no response and stable disease respectively. O.S. at 12, 24, and 36 mths. was 12/14, 11/16 and 1/12 pts.; 10/14, 7/16, 0/12 pts. and 8/14, 6/16 and 0/12 pts. respectively in three groups. Conclusions: Brisk and absent TIL correlated with favorable and unfavorable response to ICI treatment of MM while non-brisk TIL showed intermediate outcomes. Larger data set could help validate our findings.

    Kurzfassung: e21514 Background: Tumor infiltrating lymphocytes (TILs) in the tumor microenvironment generate anti-tumor immunity and are associated with response to immune checkpoint inhibitor (ICI) therapy of melanoma. However, likelihood of response to ICI therapy depends upon intensity of TILs, proportion of effector and regulatory T cells and age. Methods: In a research study approved by the Institutional Review Board of University of Connecticut, we retrospectively analyzed outcome of patients diagnosed with cutaneous melanoma between 2009 and 2019 and developed unresectable stage III or stage IV disease requiring ICI treatment. Patients were stratified by age ( 〈 75 and 〉 75 years old) and TILs at the primary cutaneous melanoma site categorized as brisk (present throughout vertical phase), non-brisk (present in one of more foci of vertical phase) or absent. Patient’s age at the time of metastases, as well as 12-month and 24-month overall survival (OS) following ICI treatment was recorded. Results: A total of 93 patients were screened, and 68 were included for analysis of survival outcome. Patients had to receive at least one dose of ICI treatment at UConn Health and had available data on TILs of primary cutaneous melanoma. In patients over 75 years of age, those with brisk TILs had an increased 24-month survival compared to those with non-brisk or absent TILs (100% vs. 45%, p = 0.04). In patients 〈 75 years of age, the 24 month survival was similar in those with brisk and non-brisk or absent TILs (67% vs. 69%, p = .91). There was no significant difference in overall survival between patients 〈 75 or 〉 75 years with brisk TILs (67% vs. 100%, p = .19). Additionally, in patients with non-brisk or absent TILs, there was a not quite significant difference in survival between those 〉 75 vs 〈 75 years (45% vs. 69%, p = .09). Conclusions: Our findings suggest that intensity of TILs in primary cutaneous melanoma is predictive of outcome following ICI treatment of advanced melanoma in patients over 75 years of age. These findings support possible interaction between qualitative differences of TILs and patient age. Our findings may help identify older melanoma patients who may benefit from ICI treatment.

    Kurzfassung: e21553 Background: Cutaneous squamous cell carcinoma (CSCC) arising from epidermal keratinocytes is highly curable with surgery. Functional anti-cancer immunity is protective of CSCC and high mortality due to local or systemic dissemination is seen in pts. with immune deficiency. ICI treatment is a logical FDA approved option that result in improved outcomes in affected pts. We report our experience in LACSCC pts. receiving ICI treatment and describe correlation between pt. characteristics, tumor histology and treatment outcome. Methods: Following Institutional Review Board approval, we did a retrospective analysis of LACSCC pts. receiving ICI therapy at the Neag Cancer Center who received at least one dose of ICI between 2018-2023. Analysis includes pt. demographics, relevant comorbidities, medications, and tumor histology and tumor infiltrating lymphocytes (TILs) of tumors reviewed with dermatopathologist. Results: Between 2018-2023, 12 pts. with LACSCC met the criteria for analysis. Median age 77.5 years (yrs.), (range 65-102), 9 males, 3 females, tumors sites - head and neck region 8 pts., torso 2 pts., legs 2 pts. Relevant past medical history included treatment of prostate cancer 3, chronic lymphocytic Leukemia 1, psoriasis 2 (one received anti TNF treatment), and MGUS, Parkinson’s disease and dementia in 1 each. Majority of pts. had significant smoking history (9/12), lymphopenia in 8 out of 12 pts. Tumors were poorly differentiated in 6 out of 12 pts. Brisk TILs was present in 7 and non-brisk TILs in 5 pts. 3 pts. with brisk TILs achieved complete remission (CR), one very good partial response (VGPR), 1 partial response (PR) and 2 not evaluable for response. Out of 5 pts. with non-brisk TILS, one achieved CR, one achieved VGPR, 1 PR, 1 stable disease (SD), and 1 progressive disease (PD) in a pt. who received anti TNF treatment of psoriasis. 9 patients are alive between 1 week and 50 months after initiation of treatment. 3 pts. died, one of PD, one of bacterial sepsis and one of Covid. Conclusions: High risk LACSCC affected males with smoking histories in the majority. Durable responses following ICI treatment occurred irrespective of age, while resistant disease was noted in 1 pt. with previous anti TNF treatment. Brisk TILs predicted high response rate and durable responses although some pts. with non-brisk TILs also showed favorable outcomes. Association with previous cancer and macular degeneration may reflect underlying immune deficiency. Three pts. developed infection within two weeks of ICI treatment (urinary tract infection, wound infection, Covid). More studies will shed light at factors compounding immune deficiency and safety of this treatment in a high-risk population.

    Kurzfassung: e17534 Background: The most recurrent structural chromosomal aberration in HPV associated cervical cancer is gain of the 3q26 locus testing of which has clinical utility in management of patients with cervical lesions. A significant proportion of OPSCC are HPV mediated, suggesting the possibility of a common disease mechanism. The objective of this study is to determine the potential clinical validity of assessing 3q gain as a biomarker in the management of patients with HPV associated OPSCC. Methods: An oral swab using a cytological brush was obtained of the region containing visualized tumor site in newly diagnosed HPV associated OPSCC patients following written informed consent of an IRB approved protocol at the University of Connecticut. The swabs were obtained at the diagnosis and serially after chemotherapy and/or chemo-radiotherapy as well as at 3 months after treatment completion. The specimens’ 3q gain status was determined by fluorescent in situ hybridization (FISH) analysis, utilizing robotic fluorescence microscopy for detection of rare cells demonstrating high 3q26 copy number Results: 54 specimens were collected from 13 patients, of which slides were prepared, hybridized and analyzed from 50. Data was not available in four specimens due to insufficient cells while for eight patients, multiple specimens were obtained before, during and after 3 months of treatment. Depending on the specimen’s cellularity, up to 170,969 cells were analyzed. Cells with 〉 4 copies of the 3q26 locus were detected in 32 of the 50 analyzable specimens. For several patients, the number of cells with more than four 3q26 signals detected in the later time points of treatment was lower than the number detected at diagnosis. Conclusions:This preliminary dataset demonstrates the ability to detect gain of the 3q26 locus in cells collected by cytological brushing of the region containing an OPSCC. The approach offers the possibility of a minimally invasive method to determine the 3q26 gain status as a reliable biomarker of HPV associated OPSCC that might have value in early diagnosis and management.

    Kurzfassung: e21026 Background: Recent studies have indicated that immune checkpoint inhibitor treatment of metastatic melanoma is effective irrespective of older age. However, in the real world setting, not all older patients (pts.) diagnosed with high-risk cutaneous melanoma have same levels of immune function due to wide variation of older age and aging associated diseases that adversely influence it. Frailty associated with co-morbidities, autoimmunity, cancer, and their treatments are three such conditions that influence treatment outcomes following immune based treatment of melanoma in older subjects. To better understand this interaction between melanoma, aging-associated diseases and potential outcomes following immune checkpoint inhibitor treatment in the real world, we reviewed clinical data of elderly melanoma pts. from the University of Connecticut's Neag Cancer Center following an IRB approval. Methods: We retrospectively reviewed clinical characteristics of elderly pts. diagnosed with high-risk cutaneous melanoma (Stage IIC, III, IV) at the University of Connecticut from 2012-2019. Pts. over the age of 60 years were divided into two main groups: Group I ("Fit elderly") and Group II ("Elderly with immune suppressive conditions"). Group II pts. were further divided into three subgroups: A ("Co-morbidities and frailty"), B ("Autoimmunity and its treatment") and C ("Cancer and its treatment"). Results: From 2012-2019, a total of 56 elderly pts. diagnosed with high-risk cutaneous melanoma were stratified as the following: Group I - 31 pts. (55%) and Group II - 25 pts. (45%); among the Group II pts., Group A contained 14 pts. (56%), Group B 5 pts. (20%), and Group C 6 pts. (24%). The median age for all 56 elderly pts. was 77 yrs. (range 61 to 99). In Group I, the median age was 73 yrs. (range 61-91). In Group II, the median age was 82 years (range 66-99); A median age 85 yrs (range 66-99), B median age 78 yrs (range 66-86), and C 80.5 yrs. (range 66-86). 9 out of 56 pts. (16%) did not receive immune checkpoint inhibitor treatment, of which 7 pts. (56%) were frail and 2 pts. (22%) were non-frail. Conclusions: Our data indicate that the existence of significant clinical heterogeneity among high-risk elderly melanoma pts. encountered in the community setting reflects a wide spectrum of immune function. Larger studies stratifying elderly subjects by co-morbidities and immune suppressive conditions will help shed accurate light on clinical relevance of immune based treatment of melanoma in older subjects.

    Kurzfassung: e21135 Background: To understand the dynamics of anti tumor immune responses (IR) in the setting of the ageing immune system, we examined immunologically relevant gene transcripts in formalin fixed paraffin embedded (FFPE) primary cutaneous melanoma (PCM) samples derived from five young (age 〈 50 years) and five elderly (age 〉 or=70 years) patients by qRT-PCR. Methods: A total of 10 FFPE tumor blocks were collected between 2004-2007 of patients with PCM at the University of Connecticut Health Center. Total RNA was extracted from FFPE tissue sections and random primed cDNA was generated. Pre amplification using pooled Taqman assays and Universal PCR Master Mix (Applied Biosystems, USA) was performed for 14 cycles to ensure an adequate amount of starting material for qPCR. Using 15 ng total RNA, the quantification of human IR genes (IL-2, INFg, TNFa, TGFb1, IL-10, Foxp3, and IDO-1) and transcripts of succinate dehydrogenase (SDHA) (as endogenous control) was accomplished by qRT-PCR amplification of a cDNA using TaqMan Universal PCR Master Mix and TaqMan gene expressions assay probes. All reaction assays including that of SDHA were performed in triplicate on an ABI 7500 Fast system (Applied Biosystems). Cycle threshold (Ct) values for each mRNA were normalized to SDHA (DCT) and represented as RQ=2 -DCT . The average RQ was calculated for all ten samples in both cohorts and Student’s T-test was performed to evaluate the statistical significance of the IR gene expression. Results: While no significant difference of expression of Th1 cytokines (IL-2, IFNg, TNFa) or Th2/3 cytokines (IL-10, TGFb) could be detected within the two groups, FOXp3 expression was significantly decreased in PCM in the elderly. Conclusions: Our results suggest ageing may be associated with less regulatory responses in situ in PCM and that more expanded analyses of the nature of the IR in PCM are likely to provide information with implications on prognosis and immune based treatment options for elderly PCM subjects.

    Kurzfassung: e22016 Background: While immune checkpoint inhibitors (ICIs) have improved the survival rates of metastatic melanoma in recent years, immune-related adverse events (irAEs) remain a major toxicity. Studies have established that pre-existing autoimmunity increases the risk of severe irAEs following ICI therapy (1). Melanoma is common cancer in older patients, and older age is believed to be a risk factor of autoimmunity. However, there is controversy concerning the influence of age increasing the risk of irAEs between clinical trials, which exclude patients with confirmed or suspected autoimmunity, and less-selective but lower-power case reports (2). In order to understand potential irAE risk following ICI treatment, we measured the prevalence of pre-existing autoimmune disease by age and cancer type. Methods: We studied 293,938 patients aged 18-106 years old who were treated at the University of Connecticut Health Center between 2000 and 2018 using GE Centricity’s IDX database. Patients were organized into four study groups based on International Classifications of Diseases codes (ICD-9 and ICD-10), specifically primary melanoma and three comparisons groups: non-cutaneous neoplasms alone, melanoma with non-cutaneous neoplasms, and patients without cancer history. A list of 340 ICD codes corresponding to 105 autoimmune conditions were queried. Results: Non-cutaneous cancer, in the absence or presence of melanoma, was associated with a higher prevalence of autoimmunity (27.0%, 29.4%, respectively) compared to the rates in patients with melanoma alone and those without cancer history (11.1%, 8.7%, respectively, p 〈 0.05). In patients with both melanoma and non-cutaneous cancers, those with metastases had an 11.7% increase in autoimmune prevalence compared to patients without metastases (p 〈 0.0001), the largest metastasis-associated increase observed across all cancer groups. Lastly, a logistic regression demonstrated that age is weakly correlated with autoimmunity (r = 0.01, p 〈 0.0001). Conclusions: The findings suggest that a history of metastasis, non-cutaneous cancer, and advanced age are associated with a higher prevalence of pre-existing autoimmunity in melanoma patients. As ICIs are indicated for metastatic melanoma, our findings warrant future studies and careful risk assessment of autoimmunity in senior patients.

    Kurzfassung: Back ground: Metastatic melanoma is an aggressive tumor of the epidermal melanocytes with high mortality rates in patients. The anti- melanoma immune response has been extensively studied while immune based treatment strategies are showing promising activity in melanoma patients. A number of immune characteristics are evaluated as predictive and prognostic biomarker. Methods: With approval from Institution's regulatory board, we analyzed T cells from peripheral blood of 12 metastatic melanoma patients for baseline frequency of T cells reacting against melanoma related Mart-1 27-35 epitope. We expanded CD 8+ T lymphocytes by exposing them to the Mart-127-35 epitope pulsed on autologous mononuclear cell derived antigen presenting cells ex vivo. Using magnetic bead separation techniques, we also isolated from the peripheral blood CD4+CD25+ (naturally occurring Treg) and CD4+CD25- cells and analyzed in vitro proliferation of CD4+CD25- T cells in response to anti CD3 antibody and PHA and analyzed the effects of CD4+CD25+ cells on their proliferation. Finally, we induced CD4+ T cells into Th1 or Th2 type responses and analyzed their function in vitro. Results: There was variable degrees of CD8+effector T lymphocytes responses to the antigens in in vitro cultures from all the patients studied and their cytokine profile noted. The percentage of nTreg activity in the PBL averaged about 5% that demonstrated suppression of the CD4+CD25- T cells proliferation in response to anti CD3 antibody in about 50% of patients, but lacked suppression activity in about 50% of the patients. It was possible to generate Th1 type cells from all the patients but generation of the Th2 type cells was limited to 50%. Favorable immune characteristics were observed in majority of the patients who are responding to the treatment. Conclusion: Our findings suggest that in vitro functional T cell immune characteristics could be examined in patients diagnosed with metastatic melanoma. Examination of these characteristics in larger number of patients diagnosed with melanoma might provide predictive marker for immune intervention. Citation Format: Upendra P. Hegde, Sidharth S.
