Metachronous head and neck osteosarcoma in an elderly patient: A rare case report with prior verrucous carcinoma

Background: Chronic myeloproliferative neoplams (CMN) are totally the most common chronic leukemias among the elderly persons in the structure of morbidity by hematologic malignancies with primary bone marrow involvement, being characterized in the advanced stages by a severe, relapsing evolution and unfavorable prognosis, with negative socio-economic impact. Objectives of the Study: Evaluation of the diagnosis and management options in chronic BCR-ABL-positive and BCR-ABL-negative myeloproliferative neoplasms in elderly patients in order to upgrade an approach to hematologic oncology care. Material and Methods: A clinico-analytical, descriptive, prospective-retrospective study was accomplished along with the narrative review of the international literature on the subject. The study included 91 elderly patients with chronic myeloid leukaemia (CML), primary myelofibrosis (PMF), and polycythemia vera (PV) who were followed and treated at the Institute of Oncology from 1995 to 2021. In regard to the impact scale, 29 relevant primary sources were distinguished and selected with a scientific, reproducible and transparent approach to the subject under discussion, followed by the data extraction and analysis. Results: Thirty-four (37.3%) patients with PMF, 26 (28.6%) – with CML and 31 (34.1%) – with PV were diagnosed in the elderly age groups and followed up by our study. The age group of 60-69 years dominated in CML (22 cases or 84.6%), constituting 25 (80.6%) cases in PV, and 25 (73.5%) - in PMF. The one- and 5-year overall survival (OS) in CML patients aged greater than or equal to 60 years treated with tyrosine kinase inhibitors (TKIs) was 97.6% and 79.8%, being lower as compared with the same indicators in the totality of CML. In elderly PV patients the OS over one year constituted 100%, over 5 years – 93.5%, over 10 years – 76.4%, being lower within 5-10 years than those registered in all patients with PV (over one year – 100%, 5 years – 98.6%, 10 years – 85.9%). Although the relapse rate was lower in patients treated with busulfan as compared to those managed with hydroxycarbamide, there was no significant difference in the OS of the elderly PV patients undergoing chemotherapy with these antineoplastic agents. As stipulated in the recent bibliographic databases, a significant rate of patients with CMN experienced the reduced work hours, discontinued employment, and medical disability: PMF – 38%, 35%, 33%, and PV – 33%, 28%, and 15%, respectively. Conclusions: The long-term results of treatment in elderly patients with CMN proved to be inferior to those in CMN totality because of the development of age-related diseases and vascular events on the account of the increased values of leukocytes and platelets. The targeted treatment with TKIs remains a first-line management option for CML patients of 60 years and more. In the elderly PV patients no significant difference was revealed in short- and long-term outcomes of chemotherapy with busulfan and hydroxycarbamide in combination with phlebotomy, being totally superior to those in PMF patients.

Endoscopic submucosal dissection (ESD) is a standard treatment in Japan for early gastric neoplasms. With an increase in elderly population, the number of elderly patients in whom ESD performed has also steadily increased. The aim of study was to evaluate the effectiveness of and problems associated with ESD for early gastric neoplasms in elderly patients. Subjects were 514 patients (586 lesions) with early gastric neoplasms performed ESD at two institutions. The patients were classified into an elderly group (age ≥ 75 years) and a nonelderly group (age < 75 years). We compared the characteristics of patients and lesions, treatment results, ESD-related complications and prognosis between the two groups. The elderly group included 200 patients (229 lesions), and the nonelderly group included 314 patients (357 lesions). The incidences of underlying disease, such as hypertension and heart disease, and the rate of antiplatelet agents use were significantly higher in the elderly group. En bloc and curative resection rates were high in both groups. The bleeding rate was significantly higher in the elderly group. Residual disease or recurrence rates were very low in both groups. The death rate due to other diseases was significantly higher in the elderly group. This study demonstrates the efficacy of ESD in both elderly and nonelderly patients. However, we must be attentive to ESD-related bleeding, death caused by other diseases, and underlying diseases when we perform ESD in elderly patients.

BackgroundStandard treatments for malignant brain tumors, such as glioblastoma (GBM) and primary CNS lymphoma (PCNSL), are recently established, except for elderly patients with neuro-cognitive impairment. We investigated our experience to adjust possible therapeutic strategy for malignant brain tumors in elderly patients according to cognitive function and QOL.MethodsWe utilized medical record data from 2015 to 2022 in our facility. Fourteen patients (11 patients with GBM and 3 with PCNSL) were retrospectively analyzed for performance status before and after surgery, neuro-cognitive function, treatments, and survival data.ResultsMedian age was 76 years old, median preoperative Karnofsky performance status (KPS) was 70, median postoperative KPS was 60, and median score of mini mental state examination (MMSE) was 18/30. Several patients with GBM deteriorated on the MMSE score and KPS after surgery, and the individuals who scored < 10 on the MMSE avoided radiation thrapy, while two patients with PCNSL improved on the MMSE score and KPS. Three patients with GBM and two patients with PCNSL received standard therapies. The rest of patients received alternative therapies; three patients had medical problems for receiving standard treatment, three patients avoided radiation therapy due to cognitive impairment, and three patients declined standard treatment. Median overall survival time in GBM patients was 254 days, and two patients with PCNSL have been still alive.ConclusionsTreatments for malignant brain tumors in elderly patients are difficult, because of their comorbidities, shorter life expectancy, and cognitive impairment. On the other hand, anticancer drug therapy alone is sometimes effective and prolongs survival of those patients. Development of personalized treatment is needed focusing on cognitive function and QOL in elderly brain tumor patients.

e15690 Background: NeuroEndocrine Tumors (NETs) remain a poorly known entity, especially in older patients. The therapeutic management is multidisciplinary combining surgery, interventional radiology, chemotherapy, cancer supportive care and also geriatrics oncology. The aim of this study performed by the OncoGeriatry Coordination Unit (UCOG) of Brittany, in collaboration with the National Reference Network for the management of NET (RENATEN), was to analyze the current management of NETs in older patients (more than 75 years old) and to develop recommandations to optimize the management of elderly patients with NENs. RENATEN’s guidelines mean systematic discussion of the cases in Regional Multidiscplinary Tumor Board (MTB) dedicated to NETs (RENATEN MTB). Methods: This study is a retrospective observational study including patients aged 75 years and over, with a NET that has been diagnosed in an pathological laboratory or whose file has been discussed in a MTB (usual MTB or RENATEN MTB) between 2014 and 2017 in the Brittany area. Results: 51 patients with a median age of 79 years [75-92] have been included up until now, among whom 77% had digestive NET, 12% urological, 8% dermatological (Merkel tumor), 4% pulmonary, 2% gynecological and 2% NETs of unknown origin. Tumor grade was 1, 2, 3 and unkown in 20%, 14%, 37% and 29% respectively. Overall, 33% of the tumors were well differentiated and 63% were metastatic (synchronous metastases :78%). Only 20% of patients benefited from a geriatric oncology consultation to help the clinician in the therapeutic decision. File of 53% of patients has been discussed one time in a specialized RENATEN MTB and 57% in another MTB. No proof of discussion in MTB was found in 12%. The treatment proposed in the RENATEN MTB was effective in 85% of patients (2 patients died immediately after RENATEN MTB, 2 patients did not wish to be treated). Only 14% of patients received initial surgery, 10% radiotherapy and 41% chemotherapy. The overall survival of this cohort is 11.3 months [0.3 -89] (for grade 3, 7.9 months [0.8-21.7]). Conclusions: The rate of multidisciplinary meeting presentation has to be improved, as well as the geriatric oncology management. A cohort of more than 100 patients will be presented at the meeting and treatment response and survival data based on age class, tumor grade, histological subtypes and therapeutic strategy will be shown.

Background: Aging hinders the liver capacity to restitute its volume and function after partial hepatectomy. Concomitant hepatic parenchyma disorders and major resections may increase the susceptibility of elderly patients to worse postoperative outcome.Methods: Prospectively collected medical records of adult patients who underwent elective partial hepatectomy for malignant liver tumors at Sohag University Hospital (June 2014–May 2020) were analyzed. A group of elderly (≥65 years) were compared with a matched control group of non-elderly (&lt;65 years) patients as regards posthepatectomy liver failure (PHLF) and overall complications, including mortality. Markers associated with PHLF and postoperative death were investigated.Results: Forty-eight patients were enrolled, 24 per group. 34 were males (71%). All patients had primary hepatic malignancy or metastatic tumors. Hepatocellular carcinoma (HCC) was the most common indication for liver resection in both groups (32 patients, 66.6%). Elderly patients exhibited significantly higher grades of overall postoperative complications (p&lt;0.05). PHLF was significantly increased in the elderly group, in evident connection with significant persistence of higher bilirubin levels and reduced prothrombin concentration (p&lt;0.05) until 5th postoperative day. Subgroup analysis showed that major resections and cirrhosis correlated with increased morbidity among elderly compared with younger patients. Postoperative mortality occurred in 3 elderly cirrhotic patients, who failed to recover normal platelet count postoperatively.Conclusions: In elderly patients, major liver resection for malignant tumors is associated with worse outcome, particularly in those with coexisting cirrhosis. Predictors include early postoperative thrombocytopenia and persistent hyperbilirubinemia and coagulopathy.

The incidence of head and neck cancer is increasing. To improve the survival of head and neck cancer patients, an effective program of screening and/or chemoprevention of second malignancies is essential. An analysis of the incidence, time to development, and risk factors of second malignant tumors in head and neck cancer patients can contribute to the design of effective screening and chemoprevention programs. Eight hundred, fifty-one patients with initial squamous cell carcinoma of the larynx (n = 224), tonsils (n = 189), pyriform sinus (n = 165), oral cavity (n = 129), mobile tongue (n = 72), and base of tongue (n = 72) treated from 1978 to 1990 were analyzed for the presence of a second malignancy after initial therapy. Of these 851 patients, 544 (64%) were documented smokers and 35 (4%) were nonsmokers. No smoking information was available for 272 patients. Four hundred, fifty-four patients (53%) were consumers of alcohol and 64 patients (8%) were nondrinkers. Alcohol consumption information was not available for 333 patients. One hundred, sixty-two (19%) second head and neck carcinomas occurred in the original 851 patients. Sixty-six patients (41%) had synchronous tumors, and 96 patients (59%) had metachronous tumors. The probability of developing a second metachronous cancer 5-years after undergoing treatment for the initial head and neck cancer was 22%. Borderline statistical significance was observed in the 5-year second cancer incidence based on the site of the initial primary cancer (46% for the base of tongue, 34% for the pyriform sinus, 23% for the larynx, 18% for the oral cavity, 15% for the tonsils, and 10% for the mobile tongue). Tobacco smoking (3% for nonsmokers vs. 26% for < or = 20 pack-years vs. 42% for > 20 and < or = 40 packs/year vs. 30% for > 40 packs/year of smoking) and the consumption of alcohol (5% for non-drinkers vs. 32% for drinkers) were both statistically significant in predicting the likelihood of developing a second malignancy. Multivariate analysis revealed that the two independent variables that influenced the occurrence of a second metachronous cancer were the anatomic site of the original primary cancer and patient age. The survival rate after the second cancer was influenced significantly by the site of the second cancer (20% for a second head or neck cancer, 3% for a second esophageal cancer, and 2% for a second lung cancer). Continued smoking (20% for non-smokers vs. 5% for smokers) and continued alcohol consumption (27% for nondrinkers vs. 6% for drinkers) also adversely influenced the survival after the occurrence of a second cancer. This study confirms the high rate of second cancers in patients with initial head and neck malignancies. The development of a second malignancy is almost always fatal. Screening programs and chemoprevention trials should be directed toward cancer patients with initial head and neck cancers. Only the small subset of nonsmokers and nondrinkers should be excluded from such trials.

Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) for pseudomyxoma peritonei and appendix tumours are widespread in the world. It is unclear what should be the attitude in elderly patients. This retrospective multicenter study collected the database from ten Spanish centers from Spanish Group of Peritoneal Cancer Surgery. The study period was between November 2002 and March 2014. Seventeen patients with age greater than or equal to 75years with peritoneal carcinomatosis from pseudomyxoma peritonei and appendix tumours met the selection criteria for the study. Outcomes in terms of morbidity and mortality such as disease-free and overall survival were analyzed. Median PCI was 16 (range 6-39). Ten postoperative adverse events were detected in nine patients (44.4%). 28% were grade I-II and 17% were grade III-IV. Disease-free survival at 1 and 3years was 67 and 44%, respectively. Overall survival at 1 and 3years was 100 and 88%, respectively. Only cytoreduction was related to worst disease free survival after univariate (p=0.007) and multivariate (OR 11.639, 95% CI 1.24-109.74, p=0.03) analyses. Cytoreduction was related to the worst overall survival after univariate analysis (p=0.046). Cytoreductive surgery and HIPEC for pseudomyxoma peritonei and appendix tumours in elderly patients it is a procedure with feasible postoperative morbi-mortality and survival outcomes. researchregistry1587 (retrospectively registered).

Little is known about the outcomes of endoscopic submucosal dissection in elderly patients with superficial squamous esophageal neoplasms. To assess the efficacy and safety of endoscopic submucosal dissection for superficial squamous esophageal neoplasms in elderly patients (≥65 years) compared with non-elderly patients. All patients with superficial squamous esophageal neoplasms receiving endoscopic submucosal dissection were retrospectively analyzed. Among them, 130 were aged 65 or older (group A), and 201 were aged younger than 65 years (group B). Therapeutic efficacy, adverse events, and follow-up data were evaluated. Group A had a higher prevalence of concomitant diseases than group B (52.3% vs. 14.9%, respectively). R0 resection rate was 82.3% in group A and 84.6 % in group B (P = 0.717). The curative resection rate was 80.8% in group A and 83.6% in group B (P = 0.653). The rate of procedure-related non-cardiopulmonary adverse events was 20.8% in group A and 16.9% in group B (P = 0.377). The incidence of cardiopulmonary adverse events during or after the procedure was 6.2% in group A and 2.5% in group B (P = 0.094). No procedure-related mortality was reported in either group. Endoscopic submucosal dissection is effective and safe for treating superficial squamous esophageal neoplasms in elderly patients.

P2.05-010 Stereotactic Radioterapy (SBRT) for Primary and Metastatic Lung Tumors in Elderly Patients: Topic: Clinical Outcome

We determined the impact of sarcopenia on the treatment outcomes of malignant bone and soft tissue tumors in elderly patients. We retrospectively reviewed 76 patients (age ≥65 years) who were treated for malignant bone and soft tissue tumors. Sarcopenia was assessed by measuring the cross-sectional area of the psoas muscles at the L3 vertebra from preoperative computed tomography images and categorized using the total psoas area/m 2 (TPA/m 2 ) ≤5.0 cm 2 /m 2 . The patients' clinical data were then evaluated. The operation time, length of hospital stay, and median overall survival were not different between the sarcopenia (n=41) and no-sarcopenia (n=35) groups. The local recurrence rate (p=0.01) and incidence of postoperative complications (p=0.02) significantly differed between both groups. The TPA/m 2 of both groups significantly decreased at the final follow-up. Sarcopenia negatively influenced wound healing and local recurrence, and was significantly exacerbated postoperatively in all elderly patients.

16035 Background: Elderly cancer patients are underrepresented in cancer services utilization and clinical research in India. National data on providers’ knowledge, attitude and practices with regard to elderly cancer patients is sparse and is urgently required to address needs of this vulnerable and growing population. Methods: A self administered questionnaire was mailed to nationally representative sample of practicing oncologists all over India. 112 Oncologists (Medical Oncologists-51%; Radiation Oncologists-25%; Surgical Oncologists-20%; allied fields-4%) responded out of 250 mailed Questionnaires. Results: A designated Geriatric Oncology unit is in existence in very few (&lt;5%) centers. Majority (51%) considered patients with chronological age of &gt;60 years as elderly for India. Although 75% of elderly patients receive some therapy, only 50% of potentially curable patients and a similar percentage of potentially incurable patients receive standard of care. Also, 50% patients require modification in their treatment and only two-third of treated patients complete therapy. The existent barriers to treatment included poor performance status (53%), advanced stage (16%), and co-morbidities (15%). Only 51% Oncologists always discussed and 28% always enrolled elderly patients in clinical trials. Standard of care and evidence based recommendations for elderly patients were felt to be lacking by 49% and 92% of respondents respectively. The need of separate trials for elderly and a separate discipline of Geriatric Oncology was voiced by 93% and 89% of respondents respectively. Major differences in treatment practice between medical oncologists and non medical oncologists are shown in table . Conclusions: Treatment practices and accrual of elderly cancer patients in clinical trials in India is far from optimal. Formation of a National Geriatric Oncology society and creation of designated Geriatric oncology services at key centers may enhance the understanding and clinical care of this population.

BackgroundRenal cell carcinoma (RCC) is the most common renal malignant tumor in elderly patients. The prognosis of renal cell carcinoma with distant metastasis is poor. We aim to construct a nomogram to predict the risk of distant metastasis in elderly patients with RCC to help doctors and patients with early intervention and improve the survival rate.MethodsThe clinicopathological information of patients was downloaded from SEER to identify all elderly patients with RCC over 65 years old from 2010 to 2018. Univariate and multivariate logistic regression analyzed the training cohort's independent risk factors for distant metastasis. A nomogram was established to predict the distant metastasis of elderly patients with RCC based on these risk factors. We used the consistency index (C-index), calibration curve, and area under the receiver operating curve (AUC) to evaluate the accuracy and discrimination of the prediction model. Decision curve analysis (DCA) was used to assess the clinical application value of the model.ResultsA total of 36,365 elderly patients with RCC were included in the study. They were randomly divided into the training cohort (N = 25,321) and the validation cohort (N = 11,044). In the training cohort, univariate and multivariate logistic regression analysis suggested that race, tumor histological type, histological grade, T stage, N stage, tumor size, surgery, radiotherapy, and chemotherapy were independent risk factors for distant metastasis elderly patients with RCC. A nomogram was constructed to predict the risk of distant metastasis in elderly patients with RCC. The training and validation cohort's C-indexes are 0.949 and 0.954, respectively, indicating that the nomogram has excellent accuracy. AUC of the training and validation cohorts indicated excellent predictive ability. DCA suggested that the nomogram had a better clinical application value than the traditional TN staging.ConclusionThis study constructed a new nomogram to predict the risk of distant metastasis in elderly patients with RCC. The nomogram has excellent accuracy and reliability, which can help doctors and patients actively monitor and follow up patients to prevent distant metastasis of tumors.

The authors' objective was 2-fold: 1) to compare outcomes of microsurgical resection for vestibular schwannoma (VS) between patients aged 70 years or older and patients younger than 70 years and 2) to test the hypothesis that symptomatic tumors in elderly patients represent a more aggressive variant of VS than those in younger adults, resulting in increased morbidity and a higher rate of recurrence after subtotal resection (STR). A retrospective matched cohort study was conducted. Patients aged 70 years or older who had undergone microsurgical resection of VS were matched to adult patients younger than 70 years; the matching was performed on the basis of surgical approach, completeness of resection, and tumor size. Associations between clinical, radiographic, and surgical data and postoperative outcome were analyzed using conditional logistic regression. Twenty patients aged 70 years or older (mean age ± SD 75.9 ± 5.3, range 70-86 years) were identified and matched to a cohort of younger adult patients (mean age ± SD 55.7 ± 13.8, range 25-69 years). The mean tumor size in both groups was approximately 3 cm. Overall, the elderly patients had a poorer preoperative American Society of Anesthesiology physical status score (p = 0.038), were more likely to report imbalance (OR 9.61, p = 0.016), and more commonly exhibited compromised balance and coordination (OR 9.61, p = 0.016) than patients in the younger cohort. There were no differences between the 2 cohorts in perioperative complications (p = 0.26) or facial nerve function (p > 0.5) at any time. The elderly patients were 13 times more likely to have long-term postoperative imbalance (OR 13.00, p = 0.013) than the younger patients. Overall, 9 tumors recurred among 32 patients undergoing STR; 6 of these patients underwent additional interventions (stereotactic radiosurgery in 5 patients and microsurgery in 1) and showed no evidence of tumor progression at the last follow-up. The median growth rate of the recurrent tumor in the 6 elderly patients was 4.8 mm/year (range 2.1-14.9 mm/year) and, in the 3 control patients, 2.2 mm/year (range 1.9-4.0 mm/year). Overall, the mortality data showed a trend toward statistical significance (p = 0.068) with a higher risk of death in the elderly. As the number of elderly patients with VS increases, microsurgical resection will remain an important management option for these patients. Despite a poorer preoperative physical status in elderly patients, their morbidity profiles are similar to those in adult patients younger than 70 years. However, elderly patients may require longer convalescence due to prolonged postoperative imbalance. Not surprisingly, overall diminished functional reserve and advanced comorbidities may increase the mortality risk associated with surgical intervention in the elderly patients. Finally, there was a high risk of further tumor growth following STR in the elderly patients (6 [37.5%] of 16), underscoring the need for close postoperative radiological surveillance and consideration of early stereotactic radiosurgery for the tumor remnant following the STR.

Background: The population in Japan is aging more rapidly than in any other country. However, no studies have determined the characteristics of the large population of elderly patients with colorectal tumors. Therefore, we examined the clinicopathological and molecular features of these tumors in elderly patients. Methods: In total, 1,627 colorectal tumors (393 serrated lesions, 277 non-serrated adenomas and 957 colorectal cancers) were acquired from patients. Tumor specimens were analyzed for BRAF and KRAS mutations, CpG island methylator phenotype-specific promoters (CACNA1G, CDKN2A, IGF2 and RUNX3), IGFBP7, MGMT, MLH1 and RASSF2 methylation, microsatellite instability (MSI) and microRNA- 31 (miR-31). Results: The frequency of elderly patients (aged ≥75 years) with sessile serrated adenomas (SSAs) with cytological dysplasia was higher than that of those with other serrated lesions and non-serrated adenomas (p < 0.0001). In elderly patients, all SSAs were located in the proximal colon (particularly the cecum to ascending colon). High miR-31 expression, MLH1 methylation and MSI-high status were more frequently detected in SSAs from elderly patients than in those from non-elderly patients. In contrast, no significant differences were found between older age of onset and high-grade dysplasia for traditional serrated adenomas or non-serrated adenomas in any of these molecular alterations. Conclusion: In elderly patients, all SSAs were located in the proximal colon. Furthermore, cytological dysplasia and molecular alterations were more frequently detected in elderly patients with SSAs than in non-elderly patients. Thus, careful colonoscopic examinations of the proximal colon are necessary for elderly patients because SSAs in those patients may exhibit malignant potential.
