Objective Patients with head and neck squamous cell carcinoma (HNSCC) have an increased risk of second esophageal neoplasms. The aim of the present study is to evaluate the incidence, risk factors and prognosis of second esophageal neoplasms in patients with HNSCC. Material and methods A retrospective study of 4,711 patients with index tumor in the oral cavity, oropharynx, hypopharynx or larynx between 1985 and 2020 was conducted. Results During the period analyzed 149 patients (3.2%) had a second esophageal neoplasm. The incidence of second esophageal neoplasia was 0.42% per year and remained nearly constant throughout the follow-up period. According to the results of a multivariate study, the risk factors related to the appearance of second esophageal neoplasms were a history of high alcohol consumption and the location of the primary tumor in the oropharynx or hypopharynx. The 5-year disease-specific survival rate in patients with a second esophageal neoplasm, calculated from the diagnosis of this second neoplasm, was 10.5%. Conclusions Patients with a HNSCC have an increased risk of developing of a second esophageal neoplasm. The risk factors associated with the appearance of a second esophageal neoplasm were severe alcohol consumption and the location of the primary tumor in the oropharynx or hypopharynx. (AU)

Outcomes of Surgery for Metachronous Second Primary Non-small Cell Lung Cancer

Objective: The optimal surgical approach for second primary metachronous lung cancer (MPLC) remains unclear. Our aim is to evaluate the morbidity and prognostic value based on the extent of surgical resection in MPLC. Methods: Retrospective study of 84 patients with a history of anatomical resection for lung cancer and MPLC surgically treated between January 2010 and December 2020. Results: The interval between the initial primary tumor and the second was 50.38±32.89 months. The second resection was contralateral in 43 patients (51.2%) and ipsilateral in 41 (48.8%). Thirty-six patients (42.9%) underwent a second anatomical resection, and in 48 patients (57.1%), it was non-anatomical. Postoperative complications were observed in 29 patients (34.5%) after the second lung resection. According to the Clavien-Dindo classification, 95.2% were mild (Clavien-Dindo I–II), and a single patient died (1.2%) in the postoperative period (Grade V). Prolonged air leak (p=0.037), postoperative arrhythmias (p=0.019) and hospital stay showed significant differences depending on the extent of surgery in ipsilateral resections. The main histological type was adenocarcinoma (47.6%) and the median tumor size was 17.74±11.74mm. The overall survival was 58.07 months (95% CI 49.29–66.85) for patients undergoing anatomical resection and 50.97 months (95% CI 43.31–58.63) for non-anatomical without significant differences (p=0.144). The disease-free survival after the second surgery was 53.75 months (95% CI 45.28–62.23) for anatomical resection and 41.34 months (95% CI 33.04–49.65) for non-anatomical group. Conclusion: Second anatomical resections provide good long-term outcomes and have been shown to provide better disease-free survival compared to non-anatomical resections in properly selected patients.

Postoperative Metachronous Metastasis of Bladder Cancer to Penis: A Case Report

Background: Penile metastases are extremely rare events, originating primarily from primary pelvic tumours of the prostate, bladder, and gastrointestinal tract. The underlying mechanism of bladder cancer metastasis to the penis remains unclear. Metastasis to the penis is usually considered a late manifestation of systemic spread. Therefore, the prognosis of patients with penile metastasis remains poor and their survival period is short. Therefore, reporting this rare case will help to better understand the characteristics, diagnosis, and treatment processes of the disease, with the aim of improving the accuracy and efficiency of diagnosis and treatment. Case Description: A 65-year-old male received transurethral resection of a bladder tumor. One year later, he underwent radical cystectomy because of the recurrence and progression of bladder cancer. Postoperative pathology demonstrated that the stage of bladder cancer was T3N0M0. One year later, he discovered a penile mass that gradually grew and became hard, accompanied by urinary retention, but without other clinical symptoms. The patient underwent a complete penectomy. Histopathology and immunohistochemistry results demonstrated the tumour’s origin as a bladder urothelial carcinoma. The patient received systemic chemotherapy after surgery, but died 7 months later. Conclusions: Although penile metastasis of bladder cancer typically indicates an advanced stage of the malignant tumour and poor prognosis, we recommend that male patients with a history of bladder cancer should undergo a regular clinical examination of the penis to rapidly detect the disease and receive early treatment. In this case, despite treatment measures such as systemic chemotherapy and penectomy, the patient’s prognosis remained poor (AU)

¿Está justificado hacer un screening a largo plazo para el cáncer de pulmón en los pacientes con un carcinoma de cabeza y cuello? / Is long-term screening for lung cancer justified in patients with head and neck carcinoma?

Objetivo Los pacientes con un carcinoma escamoso de cabeza y cuello (CECC) tienen un mayor riesgo de aparición de segundas neoplasias localizadas en el pulmón que la población general. El objetivo del presente estudio es evaluar la incidencia a largo plazo de segundas neoplasias pulmonares tras el diagnóstico de un CECC y considerar la conveniencia de la realización de un cribado de cáncer de pulmón en estos pacientes. Material y métodos Realizamos un estudio retrospectivo en 4.954 pacientes con un tumor índice localizado en la cavidad oral, orofaringe, hipofaringe o laringe durante el periodo 1985-2017. Resultados Durante el periodo de seguimiento 469 pacientes (9,5%) presentaron una segunda neoplasia pulmonar. La incidencia de segunda neoplasia pulmonar fue del 1,26% anual, y se mantuvo prácticamente constante a lo largo de los 25 años de seguimiento analizados. Según los resultados de un estudio multivariante, los pacientes varones, con edades comprendidas entre los 50 y los 80 años, con antecedentes de tabaquismo y con tumores localizados en la orofaringe o en la supraglotis fueron los que presentaron un mayor riesgo de segunda neoplasia pulmonar. Conclusiones Los pacientes con un CECC como tumor índice tienen un alto riesgo de segundas neoplasias localizadas en el pulmón. Para conseguir un diagnóstico precoz de estas segundas neoplasias sería conveniente establecer protocolos de cribado basados en el uso de la TAC pulmonar de baja dosis, que deberían mantenerse indefinidamente durante el periodo de seguimiento.

Objective Patients with head and neck squamous cell carcinoma (HNSCC) have a higher risk of second lung neoplasms than the general population. The aim of the present study is to evaluate the long-term incidence of second lung malignancies after the diagnosis of a HNSCC and to consider the convenience of the screening for lung cancer in these patients. Material and methods We conducted a retrospective study performed on 4,954 patients with an index tumor located in the oral cavity, oropharynx, hypopharynx, or larynx during the period 1985-2017. Results During the follow-up period 469 patients (9.5%) presented a second pulmonary neoplasm. The incidence of second lung neoplasm was 1.26% per year and remained practically constant throughout the 25-year follow-up period analyzed. According to the results of a multivariate study, male patients, aged between 50 and 80 years, with a history of tobacco use, and with tumors located in the oropharynx or the supraglottis were those with the highest risk of second lung neoplasms. Conclusion Patients with a HNSCC index tumor have a high risk of second neoplasms located in the lung. In order to achieve an early diagnosis of these second neoplasms, it would be advisable to establish screening protocols based on the use of low-dose lung CT, which should be maintained indefinitely during the follow-up period.

A rare case of metachronous ectopic breast cancer of the vulva / Un caso raro de cáncer de mama ectópico metacrónico de la vulva

Ectopic breast tissue can arise at any point along the primitive milk line, which runs from the axilla to the groin. The incidence of ectopic breast cancer ranges from 0.2% to 0.6%. We report the case of a 60-year-old woman with a history of left mastectomy for breast cancer one year prior to presentation, who presented with bilateral vulvar erosion found to be a moderately differentiated adenocarcinoma on biopsy. The extension workup being negative, a radical vulvectomy was performed. The postoperative course was uneventful, and the specimen's pathologic study revealed a vulvar localization of non-specific invasive breast carcinoma. It was positive for estrogen receptor and human epidermal growth factor receptor 2/neu, and negative for progesterone receptor. Adjuvant chemoradiotherapy was given to the patient. There is no dedicated guideline for both diagnosis and management of this particular tumor; the treatment is similar to that of orthotopic breast cancer. (AU)

El tejido de mama ectópico puede presentarse en cualquier punto de la línea de la leche primitiva, que discurre desde la axila a la ingle. La incidencia de cáncer de mama ectópico oscila entre el 0,2 y el 0,6%. Reportamos el caso de una mujer de 60 años con historia de mastectomía izquierda por cáncer de mama un año antes de la presentación, que acudió con erosión bilateral en la vulva, que fue considerada un adenocarcinoma moderadamente diferenciado en la biopsia. Siendo negativas las pruebas complementarias, se realizó una vulvectomía radical. El curso postoperatorio transcurrió sin incidentes, y el estudio de la muestra patológica reveló la localización en la vulva de un cáncer de mama invasivo no específico, que fue positivo para receptor de estrógenos y receptor del factor de crecimiento epidérmico humano 2/neu, y negativo para el receptor de progesterona. Se administró quimioterapia adyuvante a la paciente. No existen directrices especializadas para el diagnóstico y manejo de este tumor particular, siendo su tratamiento similar al del cáncer de mama ortotópico. (AU)

Predicted cardiac and second cancer risks for patients undergoing VMAT for mediastinal Hodgkin lymphoma

Background and purpose To predict treatment-related cardiovascular disease (CVD) and second cancer 30-yea. absolute mortality risks (AMR30) for patients with mediastinal Hodgkin lymphoma in a large multicentre radiation oncology network in Ireland. Material and methods This study includes consecutive patients treated for mediastinal lymphoma using chemotherapy and involved site radiotherapy (RT) 2016–2019. Radiation doses to heart, left ventricle, cardiac valves, lungs, oesophagus, carotid arteries and female breasts were calculated. Individual CVD and second cancer AMR30 were predicted using Irish background population rates and dose–response relationships. Results Forty-four patients with Hodgkin lymphoma were identified, 23 females, median age 28 years. Ninety-eight percent received anthracycline, 80% received 4–6 cycles ABVD. Volumetric modulated arc therapy (VMAT) ± deep inspiration breath hold (DIBH) was delivered, median total prescribed dose 30 Gy. Average mean heart dose 9.8 Gy (range 0.2–23.8 Gy). Excess treatment-related mean AMR30 from CVD was 2.18% (0.79, 0.90, 0.01, 0.13 and 0.35% for coronary disease, heart failure, valvular disease, stroke and other cardiac diseases), 1.07% due to chemotherapy and a further 1.11% from RT. Excess mean AMR30 for second cancers following RT were: lung cancer 2.20%, breast cancer in females 0.34%, and oesophageal cancer 0.28%. Conclusion For patients with mediastinal lymphoma excess mortality risks from CVD and second cancers remain clinically significant despite contemporary chemotherapy and photon-RT. Efforts to reduce the toxicity of combined modality treatment, for example, using DIBH, reduced margins and advanced RT, e.g. proton beam therapy, should be continued to further reduce potentially fatal treatment effects (AU)

Stereotactic body radiation therapy in the treatment of cancer patients with oligometastatic disease: a real world study

Purpose Stereotactic body radiation therapy (SBRT) is a treatment modality with curative intent for oligometastatic cancer patients, commonly defined by a low-burden metastatic disease with 1–5 systemic metastases. Better knowledge of the clinical profile and prognostic factors in oligometastatic cancer patients could help to improve the selection of candidates who may obtain most benefits from SBRT. The objective of this study was to describe the clinical data and outcome in term of overall survival (OS) of patients with oligometastatic disease treated with SBRT over a 6-year period. Methods From 2013 to 2018, 284 solid tumor cancer patients with 1–5 oligometastases underwent SBRT at a large university-affiliated oncological center in Barcelona, Spain. Variables related to the patient profile, tumor, oligometastatic disease, and treatment were evaluated. Results A total of 327 metastatic tumors were treated with SBRT. In 65.5% of cases, metachronous tumors were diagnosed at least 1 year after diagnosis of the primary tumor. The median age of the patients was 73.9 years and 66.5% were males. The median follow-up was 37.5 months. The most common primary tumors were lung and colorectal cancer, with lung and bone as the most commonly treated metastatic sites. Ninety-three percent of patients showed a Karnofsky score (KPS) between 80 and 100. Adenocarcinoma was the most common histological type. The median overall survival was 53.4 months, with 1-, 2- and 5-year survival rates of 90.5%, 73.9% and 43.4%, respectively. Overall survival rates of breast (67.6 months, 95% CI 56.4–78.9), urological (63.3 months, 95% CI 55.8–70.8), and colorectal (50.8 months, 95% CI 44.2–57.4) tumors were higher as compared with other malignancies (20 months, 95% CI 11.2–28.8 months) (p < 0.001) (AU)

Incidence of Bladder Cancer in Patients Undergoing Radiotherapy for Prostate Cancer

Introduction: Radiotherapeutic treatment of prostate cancer has been validated in terms of efficacy, but its relationship with the occurrence of second pelvic primary malignancy and the relevance of radio-induced toxicity is still under debate. This study analyses the occurrence of second pelvic primary malignancy as well as morbidity secondary to radiotherapy treatment in patients treated for prostate cancer. Material and Methods: Retrospective consecutive descriptive study of 317 patients who received radiotherapy treatment for prostate cancer between 2007 and 2017. Predictor variables, side effects and the appearance of second pelvic primary malignancy during a maximum follow-up of 10 years were collected. We analyse whether there is a significant relationship in the appearance of second pelvic primary malignancy and describe the clinical toxicity presented by the patients. Results: The median age was 62.27 years and the most commonly employed treatment modality was brachytherapy with IMRT (60%). 17 patients (5.4%) developed a second pelvic primary malignancy, with a median time to onset of 58 and 25 months for bladder and colon tumours, respectively. Local recurrence and mortality rates are 8% and 7%, respectively. Statistically significant association is demonstrated for the occurrence of second pelvic primary malignancy and for chronic radioinduced toxicity according to type of radiotherapy χ2 (4) = 16.34; p = 0.003 and χ2 (1) = 6.47; p = 0.011 respectively. Conclusions: In our series, the occurrence of a second pelvic primary malignancy is statistically associated with the modality of radiotherapy administered and occurrence of chronic adverse effects (AU)

Objective: Patients with nonmelanoma skin cancer (NMSC)—ie, basal cell carcinoma (BCC) or squamous cell carcinoma (SCC)—have an increased risk of developing a second skin cancer. The aim of this study was to describe the frequency, incidence per 1000 person-years, and predictors of a second skin cancer in a cohort of patients with NMSC treated with Mohs micrographic surgery (MMS). Material and methods: Prospective study of a national cohort of patients with NMSC who underwent MMS at 22 Spanish hospitals between July 2013 and February 2020; case data were recorded in the REGESMOHS registry. The study variables included demographic characteristics, frequency and incidence per 1000 person-years of second skin cancers diagnosed during the study period, and risk factors identified using mixed-effects logistic regression. Results: We analyzed data for 4768 patients who underwent MMS; 4397 (92%) had BCC and 371 (8%) had SCC. Mean follow-up was 2.4 years. Overall, 1201 patients (25%) developed a second skin cancer during follow-up; 1013 of the tumors were BCCs (21%), 154 were SCCs (3%), and 20 were melanomas (0.4%). The incidence was 107 per 1000 person-years (95% CI, 101-113) for any cancer, 90 per 1000 person-years (95% CI, 85-96) for BCC, 14 (95% CI, 12-16) per 1000 person-years for SCC, and 2 (95% CI, 1-3) per 1000 person-years for melanoma. More men than women developed a subsequent skin cancer (738 [61%] vs 463 [39%]). The main risk factors were a history of multiple tumors before diagnosis (relative risk [RR], 4.6; 95% CI, 2.9-7.1), immunosuppression (RR, 2.1; 95% CI, 1.4-3.1), and male sex (RR, 1.6; 95% CI, 1.4-1.9). Conclusion: Patients have an increased risk of developing a second tumor after MMS treatment of NMSC. Risk factors are a history of multiple tumors at diagnosis, immunosuppression, and male sex (AU)

Population-based risk assessment of second primary cancers following a first head and neck cancer: patterns of association and difficulties of its analysis

Purpose The diagnosis of a second primary cancer (SPC) is a major concern in the follow-up of survivors of a primary head and neck cancer (HNC), but the anatomic subsites in the head and neck area are close, making it difficult to distinguish a SPC of a recurrence and therefore register it correctly. Methods We performed a retrospective cohort study using data from two population-based cancer registries in Catalonia, Spain: the Tarragona Cancer Registry and the Girona Cancer Registry. All patients diagnosed with HNC during the period 1994–2013 were registered and followed-up to collect cases of SPC. We analysed the standardized incidence ratio (SIR) and the excess absolute risk (EAR) to determine the risk of second malignancies following a prior HNC. Results 923 SPC were found in a cohort of 5646 patients diagnosed of a first head and neck cancer. Men had an increased risk of a SPC with a SIR of 2.22 and an EAR of 216.76. Women also had an increased risk with a SIR of 2.02 and an EAR of 95.70. We show the risk for different tumour sites and discuss the difficulties of the analysis. Conclusion The risks of a SPC following a prior HNC in Tarragona and Girona are similar to those previously found in other similar cohorts. It would appear to be advisable to make a revision of the international rules of classification of multiple tumours, grouping the sites of head and neck area with new aetiological criteria to better determine and interpret the risks of SPC obtained in these studies (AU)

Second primary gastric cancers in a region with an overall high risk of gastric cancer / Segundos cánceres primarios gástricos en una región con un alto riesgo global de cáncer gástrico

OBJECTIVE: To compare the incidence rates of gastric cancer among cancer survivors with those in the general population, and estimate the probability of a gastric second primary cancer being diagnosed 10 years after any other first primary cancer. METHOD: A cohort of first primary cancers (other than gastric) diagnosed in Northern Portugal between 2000 and 2006 (n=64,648) was followed until 31/12/2012 for gastric second primary cancers. Incidence rates, standardized incidence ratios and the cumulative incidence of gastric second primary cancers were calculated. RESULTS: Overall, 330 patients developed gastric second primary cancers (21.2% within two months). The incidence rate of gastric second primary cancers was higher within two months of the first primary cancer (standardized incidence ratios: 5.20 in males and 7.89 in females), particularly among survivors of cancers of the oesophagus, colon and rectum, than in the remaining period (standardized incidence ratios: 0.64 in males and 0.74 in females). The 10-year risk of a gastric second primary cancer was 0.6% (males: 0.7%; females: 0.4%). CONCLUSION: The incidence rate of gastric second primary cancers among cancer survivors was higher than in the general population only soon after the first primary cancer, and lower thereafter. Despite the high mortality, the probability of a gastric second primary cancer within 10-years of the first primary cancer was 0.6%

OBJETIVO: Comparar las tasas de incidencia de cáncer gástrico entre los sobrevivientes de cáncer con las de la población general y estimar la probabilidad de que se diagnostique un segundo cáncer primario gástrico 10 años después de cualquier otro primer cáncer primario. MÉTODO: Se siguió una cohorte de pacientes con un primer cáncer primario (excluyendo los gástricos) en el norte de Portugal entre 2000 y 2006 (n=64.648) hasta el 31/12/2012 para identificar un segundo cáncer primario gástrico. Se calcularon las tasas de incidencia, las razones de incidencia estandarizadas (RIE) y la incidencia acumulada de segundos cánceres primarios gástricos. RESULTADOS: En total, 330 pacientes desarrollaron un segundo cáncer primario gástrico (21,2% en 2 meses). La tasa de incidencia de los segundos cánceres primarios gástricos fue mayor dentro de los 2 meses posteriores al primero (RIE: 5,20 en hombres y 7,89 en mujeres), en particular entre los sobrevivientes de cáncer de esófago, colon y recto, que en el período restante (RIE: 0,64 en hombres y 0,74 en mujeres). El riesgo a 10 años de un segundo cáncer primario gástrico fue del 0,6% (hombres: 0,7%; mujeres: 0,4%). CONCLUSIONES: La tasa de incidencia de segundos cánceres primarios gástricos entre los sobrevivientes de cáncer fue más alta que en la población general solo poco después del primer cáncer, y más baja a partir de entonces. A pesar de la alta mortalidad, la probabilidad de un segundo cáncer primario gástrico a 10 años del primero fue del 0,6%

Leucemia mieloide aguda secundaria al tratamiento de los tumores ginecológicos: a propósito de dos casos / Acute myeloid leukaemia associated with the treatment of gynaecological tumours: Report of two clinical cases

Las neoplasias hematológicas secundarias representan una complicación grave del tratamiento oncológico, aunque se desconoce su incidencia real en las pacientes con tumores ginecológicos. El diagnóstico de la leucemia mieloide aguda secundaria a platinos se basa en la sospecha clínica, las alteraciones morfológicas y el estudio citogenético. A pesar de la quimioterapia paliativa y el trasplante alogénico, que está limitado a ciertos casos, su pronóstico es desfavorable. Por ello deben optimizarse las pautas terapéuticas en los tumores ginecológicos con posibilidad de obtener largas supervivencias y mantener a los pacientes en programas de seguimiento prolongado

Secondary haematological malignancies represent severe complication of cancer treatment, although their real incidence is unknown in gynaecological tumours. The usual presentation of an acute leukaemia associated with platinum is based on clinical and cytogenetic features. Diagnosis is based on clinical suspicion, morphological alterations and cytogenetic studies. Conventional chemotherapy is mainly palliative, whereas allogenic transplantation allows the cure but just a small percentage of cases, so prognosis is dismal. Thus, potential curative therapies for solid tumours should be optimized and patients maintained in long-term surveillance programs

Riesgo de aparición de segundas neoplasias y neoplasias sucesivas en pacientes con un tumor índice de cabeza y cuello / Risk of onset of second neoplasms and successive neoplasms in patients with a head and neck index tumour

OBJETIVO: Analizar la incidencia de aparición de segundas neoplasias y neoplasias sucesivas en una cohorte de pacientes con un carcinoma escamoso de cabeza y cuello. MATERIAL Y MÉTODOS: Estudio retrospectivo realizado en 4.458 pacientes con un tumor índice localizado en cabeza y cuello diagnosticados durante el periodo 1985-2016. Se llevó a cabo una evaluación de la incidencia de aparición de segundas neoplasias y neoplasias sucesivas a lo largo de un periodo de 30 años. RESULTADOS: Durante el seguimiento, un total de 1.203 pacientes (27,0%) contaron con la aparición de una segunda neoplasia, 242 (5,4%) con una tercera neoplasia, 58 (1,3%) con una cuarta y 8 (0,2%) con 5 o más neoplasias. La incidencia de aparición de segundas neoplasias fue del 3,5% anual, manteniéndose prácticamente constante a lo largo del periodo de seguimiento. Los pacientes que experimentaron la aparición de una segunda neoplasia contaron con un riesgo aumentado de presentar una tercera neoplasia, y los pacientes con una tercera neoplasia, con un riesgo aumentado de presentar una cuarta. Un 78% de las segundas, un 88% de las terceras y un 89,6% de las cuartas neoplasias aparecieron en localizaciones epidemiológicamente relacionadas con los consumos de tabaco y alcohol. CONCLUSIONES: Tras el diagnóstico y tratamiento de un tumor índice de cabeza y cuello los pacientes cuentan con un riesgo de aparición de una segunda neoplasia del 3,5% anual, y este riesgo permanece constante a lo largo del periodo de seguimiento a largo plazo

OBJECTIVE: To analyse the incidence of appearance of second and successive neoplasms in a cohort of head and neck squamous carcinoma patients. MATERIAL AND METHODS: We conducted a retrospective study with 4,458 patients with an index tumour located in the head and neck diagnosed during the 1985-2016 period. We evaluated the incidence of appearance of second neoplasms and successive neoplasms over a period of 30 years. RESULTS: During the follow-up, 1,203 patients (27.0%) had a second neoplasm, 242 patients (5.4%) a third neoplasm, 58 patients (1.3%) a fourth neoplasm, and 8 patients (0.2%) 5 or more successive neoplasms. The incidence of appearance of second neoplasms was 3.5% per year, remaining relatively constant throughout the follow-up period. The patients with a second neoplasm had a higher risk of appearance of a third neoplasm, and those with a third neoplasm had a higher risk of a fourth. Seventy-eight percent of the second neoplasms, 88% of the third neoplasms, and 89.6% of the fourth neoplasms appeared in locations epidemiologically related to tobacco and alcohol use. CONCLUSIONS: Second neoplasms after a head and neck index tumour appeared at a constant rate of 3.5% per year throughout the entire follow-up period

Incidencia de segundos tumores en pacientes con cáncer de próstata de alto riesgo según el tratamiento primario aplicado / Incidence of second tumours in high risk prostate cancer patients according to the primary treatment applied

Introducción y objetivos: La aparición de segundos tumores primarios en pacientes con cáncer de próstata de alto riesgo debe tenerse en cuenta en la evolución natural de la enfermedad. Nuestro objetivo es evaluar la influencia del tratamiento primario con intención curativa de dichos pacientes en el desarrollo de segundos tumores primarios. Material y métodos: Estudio retrospectivo de 286 pacientes diagnosticados entre 1996 y 2008, tratados mediante prostatectomía radical (n = 145) o radioterapia y bloqueo androgénico (n = 141). La homogeneidad de ambas series fue analizada con el test de la Chi-cuadrado para las variables cualitativas y la t de Student para las cuantitativas. Se realizó un análisis multivariante mediante regresión de Cox, para evaluar si el tipo de tratamiento primario influía en el desarrollo de segundos tumores. Resultados: La mediana de edad fue de 66 años, y la mediana de seguimiento de 117,5 meses. Al final del seguimiento, 60 pacientes (21%) habían desarrollado un segundo tumor primario. En el grupo de prostatectomía se localizó en la pelvis en 13 (9%) casos y en 8 (5,7%) casos en los tratados con radioterapia y hormonoterapia (p = 0,29). Las localizaciones más frecuentes por órganos fueron: colorrectal en 17 (28,3%) pacientes, pulmón en 11 (18,3%) y vejiga en 6 (10%) pacientes. En el análisis multivariable, los tratados con radioterapia y hormonoterapia duplicaban el riesgo de segundo tumor (HR = 2,41, IC95%: 1,31-4,34; p = 0,005) con respecto a los pacientes tratados con prostatectomía. La edad y la radioterapia de rescate no se comportaron como factores predictores independientes. Conclusiones: La aparición de un segundo tumor primario se relacionó con el tratamiento primario administrado; así, los tratados con radioterapia y privación androgénica multiplicaron por más de 2 su riesgo

Introduction and objectives: The onset of second primary tumours should be considered in high-risk prostate cancer patients in the natural course of the disease. Our aim was to evaluate the influence of primary treatment with curative intent for these patients on the development of second primary tumours. Material and methods: A retrospective study of 286 patients diagnosed between 1996 and 2008, treated by radical prostatectomy (n = 145) or radiotherapy and androgen blockade (n = 141). The homogeneity of both series was analysed using the Chi-squared test for the qualitative variables, and the Student's t-test for the quantitative variables. A multivariate Cox regression analysis was performed to assess whether the type of primary treatment influenced the development of second tumours. Results: The median age was 66 years, and the median follow-up was 117.5 months. At the end of follow-up, 60 patients (21%) had developed a second primary tumour. In the prostatectomy group it was located in the pelvis in 13 (9%) cases, and those treated with radiotherapy and hormonotherapy in 8 (5.7%) cases (P = .29). The most common organ sites were: colo-rectal in 17 (28.3%) patients, the lung in 11 (18.3%), and the bladder in 6 (10%) patients. In the multivariable analysis, the risk of a second tumour doubled for those treated with radiotherapy and hormonotherapy (HR = 2.41, 95%CI: 1.31-4.34, P= .005) compared to the patients treated by prostatectomy. Age and rescue radiotherapy did not behave as independent predictive factors. Conclusions: The onset of a second primary tumour was related with the primary treatment given; thus the risk for those treated with radiotherapy and androgen deprivation therapy more than doubled
