    Abstract: 804 Background: Physical capability describes the ability to do the physical tasks of everyday living. Oncologists usually evaluate physical capability through anamnesis generating a performance status (PS) score. Some authors have proposed the use of cardiorespiratory reserve, muscular strength and objective evaluation of physical activity to avoid the subjective, unreliable and non-reproducible condition of PS. Methods: Patients with a recent diagnosis of colorectal cancer who accepted to participate were evaluated at the hospital setting. Walking speed was evaluated through both one-mile walk test and six-minute walk test. VO 2max was calculated through the Kilne formula. Muscular strength was measured through dynamometry (hand-grip) and “sit to stand” test. Physical activity was objectively evaluated with accelerometers. Fatigue was evaluated through the PERFORM questionnaire (12-60). ECOG was evaluated by the medical oncologist. Results: 100 pats were recruited between March 15 and Jul 17. ECOG O/1/2 (80/14/2). 40 (40 %) were metastatic. Mean age 66 (25-81), Sex M/F; 68/32. Conclusions: Objective evaluation of physical condition is feasible at the hospital setting. There were no differences in BMI, heart rate, fatigue, muscular strength and objective functional performance (weekly PA) between localized and metastatic CRC. In metastatic pts with an excellent ECOG-PS the time to walk one mile and the estimated VO 2max could be more sensitive than ECOG to evaluate the functional capacity impairment. In pts with cancer the One- mile walk test could be superior to the Six-minute walk to estimate the cardiorespiratory fitness. The objective evaluation of physical condition is a useful additional tool to select pts for aggressive therapies. [Table: see text]

    Abstract: e18532 Background: Total body irradiation is performed as part of the conditioning regimen for patients eligible for ABMT. New techniques have been investigated to target more selectively of total medular irradiation. Purpose:In this study a preclinical investigation was undertaken to explore a treatment technique for total marrow irradiation using a volumetric modulated arc technique (VMAT) versus conformal radiation therapy. Methods: Ten patients conditioning for ABMT between the periods of April to October 2016 were evaluated. A comparative dosimetric analysis between conformal and VMAT radiation therapy techniques was performed. Treatment plan was performed by using ten arcs with three isocenters with a collimator angle between 10°-100°, optimized for energy of 6MV. The prescribed dose was 12 Gy. In order to cover the bone marrow the PTV was defined as the bones from the cranium vertex to the middle third of the femur. The organs at risk constraints had a median restriction of ≤ 10Gy. Radiation therapy integral dose, conformity, homogeneity and coverage index were evaluated. Results: The average volume of body irradiated was 52,433cc (37,221-73,968cc), the average volume of the PTV was 10,379cc (8,449-13,325cc). The average dose for the planning target volume (PTV) using conformal radiation technique and with VMAT was 15.3Gy and 13.1 Gy (p 〈 0.0001), respectively. The median dose for the organs at risk with the conformal technique was 17.5Gy and 10.4Gy for the VMAT (p = 0.0013). The median of index of conformity using the conformal technique was 5.21 and 1.99 with VMAT (p = 0.0003). The homogeneity index was 1.87 and 1.37(p 〈 0.0001) respectively. The quality of coverage was 0.82 and 0.81 (p = 0.951), respectively. The integral dose was 7,699.73 and 6,615.8 kg/Gy (p 〈 0.0001) respectively. Conclusions: For patients conditioning for ABMT requiring bone marrow irradiation the intensity modulated VMAT radiation therapy technique offers a better conformity and homogeneity index and also offers a reduction in the integral dose, suggesting the possibility of incorporating this technique in the treatment options for patients.

    Abstract: 393 Background: Notwithstanding excellent oncological outcomes reported by pivotal trials in patients with testicular germ cell tumors (TGCT), adherence to medical treatment and follow-up remains a major issue in developing countries. Studies that describe the clinical characteristics and treatment adherence of Mexican men with TGCT are lacking. Methods: We performed a retrospective analysis of all men with newly diagnosed TGCT treated at an oncology referral center in Northeast Mexico from 2014 to 2018. Results: In the analysis, 195 patients were included. Median age at diagnosis was 28 years; median time from diagnosis to first evaluation by an oncologist was 26 days. Distribution according to the laterality of the primary tumor was right, 56%; left, 43%; and bilateral, 1%. There were 14 oncological emergencies at presentation; the most frequent was choriocarcinoma syndrome, described in 5 patients. Thirty-five percent of cases were seminomatous germ cell tumors (SGCT) and 65% nonseminomatous germ cell tumors (NSGCT). The clinical stages at diagnosis were I, 36%; IS, 8%; II, 18%; and III, 38%. After risk stratification according to the International Germ Cell Cancer Collaborative Group (IGCCCG), 90% of SGCT had a good risk and 10% an intermediate risk. In NSGCT, the risk distribution was 65, 10, and 25% for good, intermediate, and poor-risk disease, respectively. After proposing treatment, the adherence rate was 81%. Of the total, 58% were lost to medical follow-up with a median time of adherence of 11.5 months. Conclusions: Despite coverage by the Mexican public health insurance system “Seguro Popular”, treatment adherence and medical follow-up abandonment is a problem among men with TGCT, which could negatively impact their prognosis. Measures must be implemented to optimize adherence in this group of patients.

    Cancer-related fatigue in cancer survivors (CS) with no active treatment.
    American Society of Clinical Oncology (ASCO) ; 2017

    Abstract: 238 Background: Fatigue is a subjective experience that should be systematically assessed at the initial visit, at regular intervals and as clinically indicated. Quality of fatigue management should be included in institutional continuous quality improvement projects. The PERFORM questionnaire (PQ) was developed among Spanish speaking patients for the assessment of fatigue. Methods: Outpatients recruited for projects in which physical condition and physical activity (PA) were evaluated, rated their fatigue severity on the PQ (12-60, being 60 no fatigue). PHUEM-01 evaluated early colon CS after finishing adjuvant treatment (AT). PHUEM-02 early breast CS at the end of AT. PH-UEM-03 evaluated colorectal CS (localized and metastatic) at the time of diagnosis. MS-04 evaluated fatigue at the time of diagnosis of different tumors (localized and metastatic). Physical condition was evaluated through the one-mile walk test (VO 2MAX ) and handgrip dynamometer. Heart rate was measured as a sign of autonomic dysfunction. PA was objectively evaluated through accelerometers generating weekly MVPA information. Results: 262 CS (63% women) were recruited, (110 breast, 119 colorectal, 14 other), mean age 60. 30% of survivors reported no fatigue. Mean PERFORM score 48,34; VO 2max 25.5 ml/kg/min; handgrip 29,14 kg; HR 75 bpm. Women, younger CS, CS with worse physical condition, higher BMI, higher HR and less active CS reported more fatigue (only sex, handgrip strength and weekly PA were statistically significant for the overall population). Breast CS reported higher scores of fatigue than colorectal CS (p 〈 0.000). For breast CS there was an association between fatigue and HR which was not seen in the overall population. Metastatic colorectal did not report worse scores of fatigue than CS with localized tumors. Conclusions: As a subjective symptom, fatigue is unpredictable and its severity and interference with daily activities can be bothersome in an unexpected population (young CS, early stages) with no active treatment. More physically active and fitter CS are less fatigued. Mechanisms underlying cancer-related fatigue could be different for different tumors. More research in prevalence, evaluation, mechanisms and management of fatigue is needed.

    Abstract: e17517 Background: Cervical cancer is the fourth most common cancer among women globally, more than 84% of cases occur in low-and middle-income countries. In Mexico is the second leading cause of cancer death in women. More than 9 of every 10 cases are caused by high-risk human papillomavirus. The interaction between inflammatory microenvironment and tumor cells has a profound impact in tumor growth and metastasis. The systemic immune-inflammation index (SII) is a novel, simple and accesible biomarker to prognosis of some malignant tumors, mainly in the situation with limited resources. Evidence is scarce about their prognostic value for locally advanced cervical cancer (LACC). Methods: We performed a retrospective analysis in a cohort of 223 LACC patients treated with concurrent chemoradiotherapy at an Oncology Reference Center in Mexico between 2010 and 2019. We collected clinicopathological and treatment data of all patientes. For each patient, SII index was calculated using the neutrophil, lymphocyte, and platelet measures obtained previous treatment. ROC curve analysis was utilized for the evaluation of optimal cut-off values for SII. Relapse-free survival (RFS) was estimated by the Kaplan-Meier method, and Odds ratio modeling used to determine risks. Results: The median age was 45.3 years (range 18-75y). Among all patients, 33.2% had obesity (BMI ≥30 kg/m2), and 32.2% had normal BMI. Two hundred cases (89%) were diagnosed with squamous cell carcinoma, with histological grade 2 in 78.5%. Based on the staging system, 43.5% presented metastasis to pelvic and/or para-aortic lymph nodes. Baseline anemia was present in 61% of all patients. All patients received platinum-containing concurrent chemotherapy with radiotherapy plus brachytherapy. Eighty-one patients (36.3%) presented recurrence of the disease. The results of the ROC curve analysis exhibited the optimal cut-off values at 6.43 x10 to the 5th power for RFS (AUC: 76.6%; sensitivity: 77.8%; and specificity: 61.3%). We stratificate patients in two groups for analysis: low-SII group with index ≤6.43 x10 to the 5th power, and high-SII group with index 〉 6.43 x10 to the 5th power. Patients with high-SII had a higher probability of having recurrence (odds 53%), and patients with low-SII had a probability of 17% for recurrence (p 〈 0.001). The odds ratio (OR) was 5.54 (95% IC, 2.97-10.32) for disease recurrence with a high-SII. In the high-SII group, the median RFS was 39 months, whereas for the low-SII group the median RFS not reached. Conclusions: In LACC patients, this study has shown that SII index was significantly associated with recurrence and RFS. LACC includes a heterogeneous group of patients. In the era of personalized medicine, this novel and accessible biomarker could be used in clinical practice to improve the accuracy of pre-treatment prognostic assessment and provide an opportunity to select patients who may benefit from tailor treatment.

    Abstract: e17079 Background: There are several reports of increased of SUV in the lymph nodes of cancer patients after immune manipulation such as the administration of vaccines and checkpoint inhibitors. However the clinical importance of these phenomena is poorly understood. The administration of two immunogenic drugs and eight peptides in HGSOC induced atypical bright zones in multiple lymph nodes and, in areas with microscopic disease where potentially we can have cancer stem cells (CSC’s). Methods: We enrolled N = 10 HGSOC after the local IRB ethic committee approval. All the patients had 3 recurrences with mPFS = 8 months of the third relapse. The last FDG-PET scan was used as basal image for the study. Blood was collected for cellular and humoral immunology analysis such as Granzyme B ELISPOT and ELISA. Tissue was used for IHC analysis for the evaluation of CD8, FOXP3, Th1, and proteins related with CSC’s. The patients received 50 mg of oxaliplatin and 30 mg of doxorubicin total dose every week four times simultaneously with multi peptide immunotherapy. A second FDG-PET scan was performed after the termination of the treatment. Results: After the treatment 100% of the patients showed intense atypical bright uptake areas in lymph nodes and in the peritoneum. There was a correlation between the brightness intensity (SUV), and the Granzyme B production (p = 0.001). We found multiple bright small lesions in the peritoneum that were not visible before treatment. We demonstrated the presence of proteins related with CSC’s in the original tumor tissue and an antibody immune response against EGFR (P = 0.005), Ape-1 (p = 0.003) and Bcl-2 (p = 0.05). Conclusions: Immunotherapy may produce hypermetabolic activity that could lead to overtreatment when evaluated by FDG-PET in HGSOC. Vaccination may activate lymph nodes and anti-cancer immune interventions may also activate CD8 and Th1 cells able to accumulate in CSC’s clusters and increased notably the SUV, which may lead to false relapse interpretation by the radiologists and oncologists.

    Abstract: e12624 Background: Obesity (BMI ≥30 kg/m 2 ) and breast cancer (BC) are two major public health concerns worldwide. Obesity has been linked with aggressive clinicopathological features and inferior survival rates in patients with BC, regardless of molecular subtype. In addition, obesity has been associated with decreased pathological complete response (pCR) rates in some BC cohorts. However, the impact of obesity on pCR rates in different BC molecular subtypes is still a subject of debate. This study aims to explore the impact of obesity on pCR rates in women with different BC subtypes in a public health-care center. Methods: Medical records of women diagnosed with primary BC between 2009 and 2020 in a center in Monterrey, Mexico were reviewed. Patients with stage II or III at diagnosis treated with neoadjuvant chemotherapy (NAC) were considered eligible. Associations between variables were examined using Fisher's exact test of independence, employing logistic regression to calculate odds ratios (OR) when appropriate. Results: A total of 559 patients with a median age at diagnosis of 48 years (range 25-85) were included. Patients were diagnosed with stages II (37%) and III (63%). The most common molecular subtype was HR+/HER2- (49%), followed by TNBC (25%), HR-/HER2+ (15%), and HR+/HER2+ (11%). Regarding BMI, a significant proportion of patients was either overweight (34%) or obese (47%). In this cohort, a total of 134 (24%) patients achieved pCR following NAC with anthracycline- and/or taxane-containing regimens. pCR rates by subtype were as follows: HR-/HER2+ (41%), TNBC (34%), HR+/HER2+ (31%), and HR+/HER2- (13%). A significant association between pCR rates and molecular subtype was found (p 〈 0.001). Overall, obesity was not significantly associated with pCR rates. However, on a stratified analysis, obese patients with HR+/HER2+ tumors had significantly decreased pCR rates compared to their non-obese counterparts (OR=0.21; 95%CI 0.05-0.93; p=0.040). pCR rates according to molecular subtype and obesity status are shown in the table below. Conclusions: Obesity has an adverse influence on pCR rates in patients with HR+/HER2+ tumors. Given the endemic nature of obesity in several low- and middle-income countries, effective programs that focus on prevention, weight reduction strategies, and health promotion are warranted. Furthermore, women should be encouraged to improve their diet and engage in regular physical activity. Efforts to elucidate potential factors that underlie lower pCR rates in obese patients with certain BC subtypes are required. [Table: see text]

    Abstract: 5511 Background: Germline BRCA1/2 (g BRCA1/2) mutations are associated with poor clinical outcomes in PC. Previous studies showed that g BRCA2 carriers present more CNV in several genes associated with more aggressive disease. These aberrations may explain the poor clinical outcomes of these patients, but larger studies are needed to confirm these findings. Methods: PROREPAIR-A is a multicenter case-control study in which g BRCA2 carriers with available diagnostic timor-tissue were matched 1:2 by Gleason and stage at diagnosis (M0 vs M1) with known non-carriers (NC). A minimum of 120 controls-60 cases were required to prove a 5yr Cause Specific Survival (CSS)-rate of 85% vs 60%. The primary endpoint was to confirm the independent prognostic value of g BRCA2 in PC CSS. In addition, we explored the prognostic role of g BRCA1 and somatic events in BRCA2, RB1, MYC, PTEN and TMPRSS2-ERG by FISH. Χ 2 , Kaplan-Meier, log-rank and cox-regression models were carried out to identify associations with baseline characteristics and outcomes: Metastases Free Survival (MFS), Time to Castration-Resistance (TTCR) and CSS. Results: A total of 80:160 matched cases-controls were initially included, but tumor tissue and clinical data were only available in 73 g BRCA2 and 127 NC. 14 g BRCA1 were also included. At diagnosis, g BRCA2 were younger (median 62.6 vs 64.5, p = 0.02) and had cT3-4 disease more often than NC (31.5% vs 9.4%, p 〈 0.01), but no other significant differences were found. Somatic BRCA2-RB1 codeletion (40.8% vs 11.8%, p 〈 0.01) and MYC amplification (51.4% vs 22.8%, p 〈 0.01) were more frequent in g BRCA2 compared to NC, but no significant differences in PTEN and TMPRSS2-ERG were observed. g BRCA2 mutations as well as somatic BRCA2-RB1 codel and MYC amplif were significantly associated with shorter CSS, MFS and TTCR (Table). MVA model confirmed the independent prognostic value of g BRCA2 (HR 1.94, p = 0.03), BRCA2-RB1 codel (HR 3.16, p 〈 0.01), MYC amplif (HR 2.36, p 〈 0.01), Gleason ≥8 (p 〈 0.01) and M1 at diagnosis (p 〈 0.01) for CSS. Conclusions: PROREPAIR-A confirmed the independent prognostic value of g BRCA2 for CSS. Somatic BRCA2, RB1 and MYC aberrations were more frequent in g BRCA2 carriers. Those alterations are associated with shorter CSS, MFS and TTCR, and may contribute to poor clinical outcomes in g BRCA2 and NC. [Table: see text]

    Abstract: e24113 Background: Chronic cancer pain generates fear and anguish in cancer patients. It is suffered by 64% of patients with metastatic or terminal disease, 59% of patients in early and intermediate stages, and 33% of patients cured from cancer. They require a psychosocial support network. This network has been proposed as an essential tool to reduce the negative impact of the symptoms and psychosocial implications of cancer on the quality of life of patients. Patients with dysfunctional family networks can add to the pain of suffering cancer when they suffered or suffer violence. Cancer and pain test all personal resources and the patient's support network where family functioning is capital for quality of life. Methods: Descriptive, comparative and correlational study. A sample was taken for convenience with the prior consent of the patients who attend the outpatient clinic of the Pain Clinic of the Oncology Service, of the University Center Against Cancer of the University Hospital “Dr. José Eleuterio González” in Nuevo León. The questionnaires were applied during a session of 25 to 30 minutes. It was requested to answer the scales to assess the level of intra-family functioning, intra-family violence, quality of life, measuring psychosocial and health variables; as well as for the detection of the type and quality of psychosocial support perceived by the subjects. Results: A total of 207 research subjects were included in the study, the average age was 49 years of age (minimum 12, maximum 81 years of age), 23% men and 77% women. Marital status: married 52%, home-based 63%; monthly income less than $120 USD (n = 75, 37%). The quality of life index and chronic cancer pain had a high linear correlation with the variables of family violence, psychosocial support, family functioning, somatic symptoms, among other variables studied. Fatigue was the symptom most frequently associated with the decrease in the quality of life index. Conclusions: The satisfaction of perceived social support is a factor associated with the quality of life in patients with chronic cancer pain, however, the number of caregivers is not. There was no relationship between the size of the network and satisfaction with it. Also, the symptoms associated with chronic cancer pain affect the quality of life, identity, social functionality and roles, which in turn impact the quality of life perceived by the patient. This study supports our comprehensive intervention programs and new protocols to promote the quality of life of cancer patients.
