Abstract
BACKGROUND The incidence rate of lung cancer in women has significantly increased over the past decade, and previous evidence has indicated a significant relationship between the elevated levels of sex hormones and the risk of lung cancer. Therefore, we hypothesized that female hormone-related cancer (FHRC) patients, including breast, endometrial, cervical, and ovarian cancer patients, may experience a higher risk of developing subsequent lung cancer. This meta-analysis aimed to identify the risk of lung cancer among FHRC patients compared to the general population. METHODS The PubMed, Web of Science, EMBASE, Cochrane Library, and CNKI databases were searched up to May 11, 2022. Standardized incidence ratios (SIRs) with 95% confidence intervals (CIs) were used to identify the risk of subsequent lung cancer after FHRC. Subgroup analyses based on the follow-up time and tumor type were also conducted. RESULTS A total of 58 retrospective cohort studies involving 4,360,723 FHRC participants were included. The pooled results demonstrated that FHRC patients had a significantly increased risk of developing subsequent primary lung cancer (SIR = 1.61, 95% CI: 1.48-1.76, P <0.001). Subgroup analysis revealed an obvious trend of increasing lung cancer risk over time (SIRs for <5 years, ≥5 years, ≥10 years, ≥20 years, and ≥30 years after FHRC: 1.32, 1.59, 1.57, 1.68, and 1.95, respectively). In addition, subgroup analysis stratified by tumor type indicated an increased risk of developing subsequent lung cancer after breast (SIR = 1.25, P <0.001), endometrial (SIR = 1.40, P = 0.019), cervical (SIR = 2.56, P <0.001), and ovarian cancer (SIR = 1.50, P = 0.010). CONCLUSION FHRC patients are more likely to develop lung cancer than the general population. Furthermore, the increased risk of subsequent primary lung cancer is more obvious with a longer survival time and is observed in all types of hormone-related cancer.

Abstract
PURPOSE To compare the risk of developing subsequent primary lung cancer among cervical cancer patients and the general population. METHODS Several databases were searched from inception to April 25, 2023. The standard incidence ratios (SIRs) with 95% confidence intervals (CIs) were combined to identify the risk for second primary lung cancer after cervical carcinoma. Subgroup analyses based on the follow-up period, age, degree of malignancy and source of SIR were conducted. All the statistical analyses were performed with STATA 15.0 software. RESULTS A total of 22 retrospective studies involving 864,627 participants were included. The pooled results demonstrated that cervical cancer patients had a significantly greater risk for lung cancer than did the general population (SIR = 2.63, 95% CI: 2.37-2.91, P<0.001). Furthermore, subgroup analyses stratified by follow-up period (<5 years and ≥5 years), age (≤50 years and <50 years), and degree of malignancy (invasive and in situ) also revealed an increased risk of developing lung cancer among cervical carcinoma patients. CONCLUSION Cervical cancer patients are more likely to develop subsequent primary lung cancer than the general population, regardless of age, follow-up time or degree of malignancy. However, more high-quality prospective studies are still needed to verify our findings.

Abstract
OBJECTIVE The aim of the study was to define the incidence, prognosis, and treatment patterns associated with synchronous lower genital tract squamous cell carcinoma (LGTSCC) among women diagnosed with any LGTSCC. MATERIALS AND METHODS Surveillance, Epidemiology, and End Results (SEER) database patients diagnosed with synchronous cervical, vaginal, vulvar, and/or anal SCC from 2000 to 2016 were included. Incidence and mortality were evaluated using Kaplan-Meier curves. Multivariable Cox proportional hazards regression was used to identify treatment patterns, risk factors, and mortality associated with LGTSCC. RESULTS Among 15,424 women with LGTSCC, 138 had synchronous LGTSCC (0.89%). Vulvar and vaginal SCC was the most common combination (49.3%), and cervical with anal SCC was the least common (1.4%). Only one patient had 3 or more primary LGTSCC. Synchronous LGTSCC was independently associated with higher mortality compared with single-site LGTSCC (adjusted hazards ratio [aHR] = 1.67; p < .001). Synchronous LGTSCC was significantly associated with older age (63 vs. 58 years, p < .001) and lower stage (adjusted odds ratio [aOR] = 0.38; p < .001) and grade of disease (aOR = 0.32; p < .001). Patients with synchronous LGTSCC were more likely to receive radiation (aOR = 1.74; p = .005) and were more likely to receive adjuvant radiation after primary surgical resection compared with single-site LGTSCC (aOR = 1.88; p = .007). Receipt of any treatment including radiation (aHR = 0.85; p < .001), chemotherapy (aHR = 0.50; p < .001), and surgery (aHR = 0.70; p < .001) was independently associated with decreased mortality hazard. CONCLUSIONS Synchronous LGTSCC is rare but is associated with increased mortality and higher rates of adjuvant radiation compared with single-site LGTSCC despite lower stage and grade at diagnosis. More research is needed to define optimal therapy for these patients.

A large population-based study. J Cancer 2020; 11:6204-6212. [PMID: 33033503 PMCID: PMC7532509 DOI: 10.7150/jca.44726] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2020] [Accepted: 06/14/2020] [Indexed: 02/07/2023] Open
Abstract
Objective: The survival of prostate cancer (PC) patients after radiotherapy (RT) has improved over time, but it raises the debate of increased risk of secondary colorectal cancer (SCRC). This study aimed to assess whether RT for PC treatment increases the risk of SCRC in comparison with radical prostatectomy (RP). Methods: A population-based cohort of PC patients treated only with RT or only with RP between January 2007 and December 2015 was identified from the Taiwan Cancer Registry. The incidence rate of SCRC development was estimated using Cox regression model. Results: In this study, total 8,797 PC patients treated with either RT (n = 3,219) or RP (n =5,578). Patients subjected to RT were elder (higher percentage of 70≧years, p < 0.0001) and more advanced clinically (stage III: 22.90% vs. 11.87%; stage IV: 22.15% vs. 13.80%, p < 0.0001), compared to those subjected to RP. More patients subjected to RT had a much higher percentage of autoimmune disease (22.34% vs. 18.75%, p < 0.0001) and osteoarthritis and allied disorders (16.31% vs. 12.98%, p < 0.0001). Besides, RT patients had a higher percentage of underlying Crohn's disease (0.25% vs. 0.05%, p = 0.0230). Although almost all selected factors were not statistically significant, they presented the positive risk of SCRC for those under RP compared with those among RT. Besides, for PC patients in clinical stage I and II, patients with RP may have borderline significantly protective effects of SCRC compared with those under RT (stage I, HR: 0.14; 95% C.I.:0.01-1.39; p = 0.0929; stage II, HR: 1.92; 95% C.I.:0.93-3.95; p = 0.0775). Kaplan-Meier curves for a 3-year-period, which demonstrated no statistical difference in the risk of SCRC free between PC patients undergoing RT and RP (p = 0.9766). Conclusion: Whether or not pelvic RT for PC is associated with an increased risk for SCRC on a population-based level remains a matter of considerable debate. From a clinical perspective, these PC survivors should be counseled accordingly and received continued cancer surveillance with regular colonoscopy follow-up.

Abstract
Background High-risk human papilloma viruses (HPV) are a causative agent of anogenital and oropharyngeal cancers. Patients treated for a preinvasive or invasive HPV-associated cancer may be at increased risk of a second such malignancy. Methods We performed a systematic review and random effects meta-analysis to estimate the risk of HPV-associated cancer after prior diagnosis. Studies reporting second cancers at anogenital and oropharyngeal sites after prior diagnoses (preinvasive/invasive HPV-associated cancer) were identified. Studies reporting standardised incidence ratios (SIRs) were included in formal meta-analyses of second cancer risk. (PROSPERO ID: CRD42016046974). Results Searches returned 5599 titles, including 60 unique, eligible studies. Thirty-two (98 comparisons) presented SIRs for second cervical, anal, vulvo-vaginal, penile, and/or oropharyngeal cancers, included in the meta-analyses. All studies (and 95/98 comparisons) reported increased cancers in the population with previous HPV-associated cancer when compared to controls. Pooled SIRs for second primary cancers ranged from 1.75 (95% CI 0.66−4.67) for cervical cancer after primary anal cancer, to 13.69 (95% CI 8.56−21.89) for anal cancer after primary vulvo-vaginal cancer. Conclusions We have quantified the increased risk of second HPV-associated cancer following diagnosis and treatment for initial cancer or preinvasive disease. This has important implications for follow-up, screening, and future therapeutic trials.

Abstract
OBJECTIVE To examine survival of women who develop metachronous uterine malignancy after definitive pelvic radiotherapy for cervical cancer. METHODS This retrospective observational study examined the Surveillance, Epidemiology, End Results Program between 1973 and 2013. Women with cervical cancer who received definitive radiotherapy without hysterectomy were examined for the diagnosis of metachronous uterine malignancy (n = 5277). Survival was compared between metachronous and non-metachronous uterine malignancies according to tumor factors. RESULTS The 10- and 20-year cumulative incidences of metachronous uterine malignancy were 0.6% and 1.2%, respectively. When compared to non-metachronous uterine malignancy, metachronous tumor were more likely to be non-endometrioid and advanced-stage (both, P < 0.001). As a whole cohort, metachronous uterine malignancy was significantly associated with decreased overall survival (OS) compared to non-metachronous tumors (hazard ratio [HR] 4.22, P < 0.001). OS was significantly worse in metachronous compared to non-metachronous malignancies, although the magnitude of statistical significance was greater for endometrioid tumors (HRs for endometrioid versus non-endometrioid: 6.17 versus 1.92). For grade 1-2 endometrial cancer, metachronous cases had significantly decreased OS compared to non-metachronous cases, a larger difference than that seen in higher grade tumors (HRs for grade 1-2 versus 3: 7.79 versus 2.15). Similarly, in early-stage endometrial cancer, metachronous cases had significantly decreased OS, with a greater HR compared to advanced-stage disease (HRs for stage I-II versus III-IV: 5.29 versus 2.29). CONCLUSION Radiotherapy-associated metachronous uterine malignancy after cervical cancer is rare but commonly presents with aggressive tumor characteristics. The impact on survival is considerably high when metachronous uterine malignancy is endometrioid, low-grade, and early-stage.

Abstract
OBJECTIVE To examine incidences and risk factors for metachronous vulvar, vaginal, and anal malignancies after a cervical cancer diagnosis. METHODS This is a retrospective study examining data from the Surveillance, Epidemiology, and End Result Program between 1973 and 2013. Cumulative incidences of vulvar, vaginal, and anal cancers after the diagnosis of cervical cancer were assessed (n = 79,050). Multivariable analysis was performed to determine independent risk factors for these metachronous cancers. RESULTS Vaginal cancer (20-year cumulative incidence, 0.57%) was the most common type of metachronous malignancy, followed by vulvar cancer (0.33%), and anal cancer (0.16%, P < 0.001). Median time to diagnosis was 5.4 years for vaginal cancer, 6.5 years for vulvar cancer, and 13.5 years for anal cancer. On multivariable analysis, metachronous vulvar cancer was associated with older age (hazard ratio [HR] per year 1.04, 95% confidence interval [CI] 1.02-1.05, P < 0.001), squamous histology (HR 2.64, 95%CI 1.38-5.05, P = 0.003), and radiotherapy use (HR 2.52, 95%CI 1.66-3.84, P < 0.001); metachronous vaginal cancer was associated with older age (HR per year 1.03, 95%CI 1.02-1.04, P < 0.001) and Black race (HR 1.73, 95%CI 1.20-2.48, P = 0.003); and metachronous anal cancer was associated with older age (HR 1.03, 95%CI 1.01-1.05, P = 0.017). Overall survival of metachronous cancer was poor (5-year rates: 46.3% for vulvar, 43.0% for vaginal, and 47.5% for anal cancer, respectively). CONCLUSION Although rare, the rate of ano-genital cancers continues to increase over time after a cervical cancer diagnosis. Long-term follow-up and surveillance after cervical cancer treatment is therefore reasonable to detect these metachronous malignancies, particularly in those with risk factors.

Abstract
To evaluate the risk of secondary primary malignancy (SPM) in patients with cervical cancer using a nationwide population-based dataset.Patients newly diagnosed with cervical cancer between 1997 and 2011 were identified using Taiwan's National Health Insurance database. Patients with antecedent malignancies were excluded. Standardized incidence ratios (SIRs) for SPM were calculated by comparing with the cancer incidence in the general population. Risk factors for cancer development were analyzed using Cox proportional hazard models.During the 14-year study period (follow-up of 223,062 person-years), 2004 cancers developed in 35,175 patients with cervical cancer. The SIR for all cancers was 1.56 (95% confidence interval, 1.50-1.63, P < 0.001). SIRs for follow-up periods of >10, 5 to 10, 1 to 5, and <1 year were 1.37, 1.51, 1.34, and 2.59, respectively. After the exclusion of SPM occurring within 1 year of cervical cancer diagnosis, SIRs were significantly higher for cancers of the esophagus (2.05), stomach (1.38), colon, rectum, and anus (1.36); lung and mediastinum (2.28), bone and soft tissue (2.23), uterus (3.76), bladder (2.26), and kidneys (1.41). Multivariate analysis showed that age ≥60 was a significant SPM risk factor (hazard ratio [HR] 1.59). Different treatments for cervical cancer, including radiotherapy (HR 1.41) and chemotherapy (HR 1.27), had different impacts on SPM risk. Carboplatin and fluorouracil independently increased SPM risk in cervical cancer patients.Patients with cervical cancer are at increased risk of SPM development. Age ≥60 years, chemotherapy, and radiotherapy are independent risk factors. Carboplatin and fluorouracil also increased SPM risk independently. Close surveillance of patients at high risk should be considered for the early detection of SPMs.

Abstract
A patient with cervical non-Hodgkin lymphoma was treated with chemotherapy. Fourteen months after the diagnosis of the lymphoma, an endometrial adenocarcinoma was detected as a secondary malignant tumor. The patient was treated with surgery followed by radiotherapy. Approximately 7 years after the diagnosis of endometrial cancer, vaginal invasive squamous cell carcinoma was diagnosed as the third primary malignancy, and a second-line palliative radiotherapy was applied. Seven months after the last radiotherapy, postradiational sarcoma in the vagina was diagnosed. Congenital and acquired immune system disorders, viral oncogenes, and various human leukocyte antigen (HLA) types were investigated. Total blood count and lymphocyte subset analysis were performed, and CD4+ lymphopenia was detected. Serologic tests were carried out for human immunodeficiency virus, hepatitis B virus, human papillomavirus, Epstein-Barr virus, and herpes simplex virus infection. Epstein-Barr virus viral capsid antigen IgG was found positive. Low-risk human papillomavirus panel was detected by Hybrid Capture method in the cervical smear. The HLA investigation revealed HLA-A2, HLA-A3, HLA-B57, HLA-B35, HLA-B4, HLA-B6, HLA-DR3, HLA-DR1, HLA-DR51, HLA-DR52, HLA-DQ6(1), and HLA-DQ7(3). The patient died because of the disease.

Abstract
With improvement in survival after cancer treatment, it is becoming increasingly important to examine treatment-related morbidity and mortality. Sarcomas can develop within the irradiated field after radiation therapy (RT) for gynecologic malignancies. We undertook a study to assess the outcome after treatment of postirradiation sarcoma (PIS) of the gynecologic tract. In reviewing our data and the literature, we compare the absolute risk of PIS and other radiation-associated second malignant neoplasms (SMNs) with the mortality risk of surgery and general anesthesia. Between 1955 and 1987, 114 patients with uterine sarcomas were seen at the University of California, Los Angeles (UCLA), Medical Center. Thirteen had a prior history of RT. Conditions for which these patients received RT included choriocarcinoma (one), menorraghia (four), cervical cancer (six), and ovarian cancer (two). RT doses were known in six cases and ranged from 4,000 to 8,000 cGy. Latency time from RT to the development of PIS ranged from 3 to 30 years, with a median of 17 years. Twelve patients were treated with surgery or additional RT. Two patients remain alive 5 months and 57 months, respectively, following salvage therapy. Five-year disease-specific survival for all patients is 17%. From our data and a review of the literature, we estimate that the absolute risk of PIS with long-term follow-up ranges from 0.03 to 0.8%. Postirradiation sarcoma of the gynecologic tract is a relatively rate event associated with a poor prognosis. Mortality risks of radiation-associated SMN are similar to mortality risks of surgery and general anesthesia. Given the large number of patients with gynecologic malignancies who can be cured or palliated with RT, concern regarding radiation sarcomagenesis should not be a major factor influencing treatment decisions.

Abstract
BACKGROUND The relative risk of second primary cancers was evaluated in 125 women with International Federation of Gynecology and Obstetrics (FIGO) Stages I and II cervical carcinoma treated radically with radiation therapy between January 1980 and December 1990. METHODS Medical records of patients were reviewed to evaluate the incidence of second malignant neoplasms. Only tumors histologically proven were scored. The annual 5-year age-specific cancer incidence data per 100,000 white women in the years 1981-1985 were obtained from the National Cancer Institute's Surveillance, Epidemiology and End Results database. The relative risks were calculated as the ratio of observed-to-expected numbers of second cancers, using person-years at risk accumulated for each individual in the study. RESULTS During the follow-up time (through December 1992), 10 women whose median age was 65.5 years at the time cervical cancer was diagnosed were found to have 11 second primary cancers. Nine of these cancers were metachronous with regard to cervical cancer and included breast (4), lung (2), myeloma (1), non-Hodgkin's lymphoma (1) and vulva(1). The metachronous tumors were diagnosed at a median age of 74 years and at median follow-up time of 34 months. Two of the cancers were synchronous with cervical cancer and included bladder (1) and thyroid (1). All of the second tumors were located outside radiation fields. None of the patients with second tumors received chemotherapy during treatment for cervical carcinoma. The relative risk of developing a second cancer of any type was 2.31 (95% confidence interval [CI] = 1.15-4.13), whereas the relative risk of developing a metachronous breast cancer was 2.64 (95% CI = 0.72-6.75). CONCLUSIONS An increased risk of second primary cancers developing was observed among 125 patients with FIGO Stages I and II cervical carcinoma, which may suggest an abnormal genetic background and/or a common etiology for the initial and second tumors. The increased risk of breast cancer occurring as a second primary is in contrast with previously published studies reporting a decreased risk of breast cancer in survivors of cervical cancer.

Abstract
PURPOSE Adjuvant radiotherapy is used increasingly in the management of rectal cancer. However, ionizing radiation is mutagenic, and, superimposed on a background of increased cellular proliferation as seen around anastomoses and in colorectal cancer patients, there is the potential for enhanced metachronous cancer risk. METHOD The influence of preoperative irradiation on both carcinogenesis and cellular proliferation at colonic anastomoses was explored in 180 adult male F344 rats. Orthovoltage x-rays were delivered to the distal descending colon by parallel opposed fields. Ninety rats received 16 Gy in one fraction; the remainder received 36 Gy in two fractions one week apart. In each irradiation group 18 rats either acted as controls or one week after radiotherapy underwent distal colotomy and repair. RESULTS We found the descending colon susceptible to radiation carcinogenesis; 26 colorectal tumors developed in the low-dose irradiation group and 47 in the high-dose group (P = 0.0008; Mann-Whitney U test, 16 vs. 36 Gy). Preferential tumor development was seen in the anastomotic region. In those animals that underwent surgery and irradiation, among the low-dose irradiation group only 3 of 72 had tumors within the descending colon compared with 21 of 72 at the anastomotic site (McNemar's test chi-squared = 40.9; P < 0.001), and in the high-dose irradiation group 5 of 72 had tumors within the descending colon compared with 36 of 72 at the anastomotic site (McNemar's test chi-squared = 22.0; P < 0.001). Anastomotic crypt cell production rates were increased for at least three months following exposure to irradiation (16 Gy: f = 15.1, P < 0.005; 32 Gy: f = 9.4, P < 0.005). CONCLUSIONS Radiation carcinogenesis is greatly enhanced at colonic anastomoses and may result from altered anastomotic proliferation. This has potentially disturbing implications in view of the increasing use of adjuvant radiotherapy for rectal carcinoma.

Abstract
From the records of the Thames Cancer Registry, 859 patients were identified, who were treated with radiotherapy for seminoma of the testis between 1961 and 1985. Second cancer incidence and mortality and also causes of non-cancer deaths in the study population were examined. Fifty-one (6%) patients died of testicular cancer, 42 within 5 years of diagnosis. There were 42 second cancers (other than second testicular cancers), and 20 deaths from second cancer (expected, 22.1--non-significant). The only subtype of cancer with a notable excess was leukaemia (4 incident cases observed; 0.64 expected; relative risk 6.2, 95% C.I., 2.7-14.8, 95% C.I., 2.7-14.7). The overall death rate from causes other than testicular cancer was not elevated (82 observed, 82.06 expected). There was some suggestion of an increase in the risk of mortality with time; for 10 or more years after treatment the relative risk was 1.31 (95% C.I., 0.95-1.81). There was no evidence of excess non-cancer deaths (62 observed, 60 expected). We conclude that there is no definite evidence from this investigation of increased risk of mortality secondary to radiotherapy; however, the excess incidence of leukaemia may be treatment-related and the cohort will be followed further.

Abstract
PURPOSE From 1956 to 1986, we have retrospectively studied 184 patients with a Stage I testis seminoma treated by orchidectomy and radiotherapy at the Institut Gustave Roussy. METHODS AND MATERIALS The 184 patients received adjuvant radiotherapy to the para-aortic and ipsilateral iliac nodes. Of the 184 patients, 133 received additional mediastinal and supraclavicular irradiation, 47 received supraclavicular without mediastinum irradiation, 98 patients received additional radiotherapy given to inguino-scrotal area. The mean dose of irradiation is 21 Gy which is the lowest dose published. The actuarial survival rate is, respectively, 96%, 93%, 83% and 77% at 5, 10, 15, and 20 years. RESULTS Four patients relapsed, and four died of progressive disease. Four patients presented cardiovascular disease, all of them had mediastinal irradiation, two were heavy smokers. Seventeen second malignancies were observed, six tumors in the contralateral testis. The actuarial risk of developing a second malignancy is 10% at 10 years, 21% at 20 years. The cure rate and relapse rate in our patients is the same as that obtained by higher dosage of irradiation. CONCLUSION We conclude that low dose of prophylactic irradiation in lumbo aortic and ipsilateral iliac lymph nodes is active and safe in the treatment of Stage I testis seminoma.

Abstract
Between 1985 and 1990, five cases of radiation-induced bladder cancer were treated at our center. The first primary neoplasm was uterine cervical cancer in three patients, uterine endometrial cancer in one patient, and Hodgkin's disease in one patient. Additional treatment for the primary neoplasm included panhysterectomy for the patient with endometrial cancer and cyclophosphamide-based combination chemotherapy for the patient with Hodgkin's disease. The mean age at development of bladder cancer was 60.4 years, and the average time interval between irradiation and development of bladder cancer was 14.6 years. All the bladder cancers were invasive. The treatment modalities included anterior pelvic exenteration in one patient, partial cystectomy in one patient, reirradiation in two patients, including the use of intraoperative electron therapy in one patient, and TUR plus endoscopic Nd:YAG laser treatment in one patient. Four patients are alive without disease at a mean follow-up period of 15 months from the diagnosis of bladder cancer.

Abstract
Chondrosarcomas of the head and neck are uncommon. Over a 35-year period (1950-1985) at our institution, 557 patients had an established diagnosis of chondrosarcoma. In 28 (5%) of these patients, the tumor was located in the head and neck region. A retrospective analysis was performed in an attempt to accurately define clinical characteristics, management, and outcome in these 28 patients. The patient population consisted of 15 males and 13 females whose ages ranged from 10 to 72 years, with a median of 38 years. Ten (36%) patients were untreated and 18 (64%) previously treated patients were referred for further management. The primary sites were maxilla (11), cervical vertebrae (7), mandible (3), skull (2), sphenoid and ethmoid sinuses (2), frontal sinus (1), nasal septum (1), and orbit (1). Lesions arising in the larynx were excluded from this study. The most common presenting symptom was a painless mass. Surgery was the definitive treatment in all patients. However, adjuvant radiation therapy or chemotherapy was utilized for residual disease in almost half of the cases (13 patients). Follow-up ranged from 5 to 35 years. Twelve (43%) of the 28 patients were known to be alive and free of disease more than 5 years after surgery. The most common cause of death was uncontrollable local disease (88%). However, only 3 of the 10 previously untreated patients developed local recurrence. For all patients, the median interval from time of first recurrence until death was 25 months (range 6 to 70 months). Positive margins in 8 of 12 patients resulted in local recurrence and eventual death.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Primary cancers of the vagina are rare. They comprise 1% to 2% of all gynecologic malignancies and occur predominantly in older women. The diagnosis of primary carcinoma of the vagina requires that the cervix and vulva be intact and that no clinical evidence of other primary tumors exist. Approximately 90% of all vaginal tumors are squamous cell in type on histologic examination. Adenocarcinoma, which is much less common (2% to 4%), is seen primarily in younger women with in utero exposure to diethylstilbestrol. In addition to exposure to diethylstilbestrol, other environmental factors have been associated with the development of vaginal tumors, including chronic irritation from pessaries, previous hysterectomy for benign disease, immunosuppression therapy, cervical irradiation, and endometriosis. Infectious causes seem to play an even more pernicious role in vaginal cancer. The two agents most often implicated are herpes simplex virus and human papillomavirus. These viruses appear to serve as cofactors in the inducement of various genital cancers, working together or with environmental agents such as diethylstilbestrol and host-related genetic abnormalities. The prognosis of vaginal cancer depends on the stage of the disease, with an overall 5-year survival rate of 80% to 90% for early stages.

Abstract
Radiation-induced cancers after radiation therapy for cancer of the uterine cervix were investigated on 11,855 patients including 5725 patients treated with radiation therapy alone, 1969 postoperative radiation therapy and 4161 surgery alone. The observed-to-expected ratios of the second primary cancer was 0.933 for the patients with radiation therapy alone and 1.074 for the patients with postoperative radiation therapy, respectively. No significant increase was observed in the risk of second primary cancers when all sites were combined. However, assessing on site by site basis, significant excess was noted for the rectum cancer, leukemia, and bladder cancer for the radiation therapy group but not for the surgery group. A significant excess of lung cancer was observed in both radiation therapy and surgery groups, which was attributed to some other causative factors. Radiation-induced cancers were suggested to develop apparently in organs involved in the irradiated field.

Abstract
Second malignancies are one of the known complications of cancer treatment. Several recent studies which have quantified the risk of treatment-induced cancers following gynecologic malignancies are reviewed. After cervical cancer, there is a 9% excess risk of second cancers, of which only 5% could be attributed to radiation therapy. Most of the treatment-related malignancies after cervical or endometrial cancer are solid tumors occurring within the radiation field. Following both cervical and endometrial cancer, there is a small increased risk of leukemia associated with radiation therapy. In contrast, after ovarian cancer, there is significantly increased risk of leukemia related to treatment with alkylating agents, which varies by drug type and total dose. The cumulative risk of leukemia and preleukemia following single agent melphalan is 11.2% +/- 2.6% at ten years; the risk after cyclophosphamide is 5.4% +/- 3.2%. Overall, the risk of second malignancies following treatment of gynecologic cancers is small.

Abstract
Some patients may be predisposed to the development of more than one gynecologic neoplasm. We evaluated 130 cases of synchronous or metachronous tumors among 5967 patients followed up by The Ohio State University Gynecologic Tumor Registry for the past 44 years from 1939 to 1983. Based on primary tumor site and invasive behavior, expected incidences for a specific second malignancy were calculated by the person-years method. A second malignancy of the lower genital tract occurred in patients with cervical, vulvar, and vaginal cancers, 1.6%, 4.3%, and 9.6%, respectively, which supports the theory of multicentric cancer of the lower genital tract. Prior radiation therapy was rarely associated with increased second gynecologic malignancies (two of 41 patients, 4.9%). Four patients had three gynecologic tumors.

Abstract
The Ohio State University Registry recorded 1208 uterine corpus malignancies between 1940 and 1983. Thirty cases occurred in women with a history of pelvic irradiation. Eight patients had previously been irradiated for pelvic malignancy, four of whom presented with advanced stage sarcomas and died of their disease within 14 months. This represents an increase over the expected sarcoma prevalence which is less than 5%. In contrast, the majority of women (20 of 22) previously irradiated for benign conditions were diagnosed with endometrial adenocarcinoma. In 18, the adenocarcinoma was diagnosed as Stage I, and the prognosis was only slightly less favorable than for nonirradiated women. No significant effect of age at the time of irradiation was apparent. This study of women with a history of pelvic irradiation who later developed uterine cancer demonstrates a tendency for patients previously irradiated for pelvic malignancy to present with advanced stage, extremely aggressive uterine tumors compared to those previously irradiated for benign conditions.

The risk of second primary malignancy arising after therapeutic irradiation was evaluated in the Radiumhemmet series of carcinoma of the uterine cervix treated in 1914-1965. Only tumours appearing more than 10 years after irradiation were taken into account. Comparisons of observed with expected incidence showed excess of malignancies in urinary bladder, endometrium, ovaries and rectum, but not of colon carcinoma. Comparisons were made with cohorts from the Swedish Cancer Registry.

Lifetable survival curves have been adapted to measure "time to second primary" and used to compare incidence of second primary in all patients in the Alberta Cancer Registry with a primary malignancy in cervix, endometrium and ovary. Comparisons were also obtained within each diagnostic category between patients treated or not treated with radiation. Results show that there are no statistically significant differences in the 25 years following diagnosis of the first primary in "time to second primaries" in patients with cancer of the cervix, endometrium or ovary. Similarly, within each diagnostic category, there are no differences between radiation treated patients and those not treated by radiation, when adjustments for age differences are made and when patients are selected by length of survival.

Abstract
897 patients received radiotherapy in Scotland for tumours of the testis between 1950-1969. 299 patients who died within two years of treatment, and a further 51 patients with inadequate follow-up data, were excluded from a survey of the incidence of second tumours. 547 patients with a mean follow-up of 15.4 years were included in the study. Fifty-one second and six third malignancies were found. The observed incidence is significantly higher than expected (ratio 1.87; p less than 0.001), both in the irradiated sites (ratio 1.94; p less than 0.05) and in unirradiated sites (ratio 1.99; p less than 0.01). These patients have a higher incidence of second testicular tumours (ratio 23.1; p less than 0.001). Analysis of the incidence of new malignancies in successive quinquennia after irradiation shows a significantly higher incidence in two periods. Within five years the greater incidence (p less than 0.05) is due mainly to the occurrence of second testicular tumours. In the period 15-19 years after irradiation the higher incidence (p less than 0.01) is accounted for by tumours arising in the urinary and gastro-intestinal tracts. The increased risk of developing a second cancer is low and there was no observed increase in radiation-related leukaemia.

Abstract
Serum concentrations of unconjugated estrone (E1) and 17 beta-estradiol (E2) have been measured in eight patients before and after 1.25 mg of conjugated estrogens administered intravaginally. The measurements were repeated using 2 mg of micronized estradiol administered intravaginally 1 week later to six of the women and 7 months later in one. All the patients had completed a full course of irradiation for pelvic malignancy at least 8 months prior to the study. Baseline, 1/2, 1-, 2-, 4-, 8-, and 24-hr samples were analyzed. After conjugated estrogens mean serum E2 increased 4.5-fold to peak at 163 pg/ml at 2 hr while serum E1 increased 3.2-fold to peak at 222 pg/ml at 2 hr. After micronized E2 mean serum E2 increased 89.3-fold to peak at 1250 pg/ml at 1 hr while E1 increased 3.1-fold to peak at 416 pg/ml at 2 hr. These data indicate that rapid absorption of E1 and E2 occurs through irradiated vaginal mucosa.
