Multiple primary malignant neoplasms from the black sea region of Turkey

An unusual occurrence of multiple primary malignant neoplasms: a case report and narrative review

Introduction

Multiple primary malignant neoplasms (MPMNs) are cancers presenting distinct pathological types that originate from different tissues or organs. They are categorized as either synchronous or metachronous. Nowadays, the incidence of MPMN is increasing.

Patients and methods

We present a case of a 71-year-old male patient with a medical history of hepatitis B and a family history of breast and endometrial cancers. The patient reported a nasal tip skin lesion with recurrent bleeding, and the history disclosed lower urinary tract symptoms. Further investigations revealed the coexistence of four primary cancers: basosquamous carcinoma of the nasal lesion, prostatic adenocarcinoma, hepatocellular carcinoma, and clear cell renal cell carcinoma.

Results

A multidisciplinary team cooperated to decide the proper diagnostic and therapeutic modules.

Conclusion

To the best of our knowledge, the synchronization of these four primary cancers has never been reported in the literature. Even so, multiple primary malignant neoplasms, in general, are no longer a rare entity and need proper explanations, a precise representation of definition and incidence, further work-up approaches, and treatment guidelines as well.

Clinicopathological analysis of patients with dual malignancies: A retrospective study

BACKGROUND

This study aims to report the increasing incidence of second primary malignancies to better understand the association of multiple primary cancers and the duration of their occurrence. Keeping in view the current trends in dual malignancies and to further emphasize the importance of screening and follow-up diagnosis, we reviewed the records of patients who were diagnosed with dual malignancies.

MATERIAL AND METHODS

This is a retrospective observational study. We collected data from the hospital database, of patients presenting with either histologically proven synchronous or metachronous double primaries between January 1, 2017, and December 31, 2021. The time interval to differentiate between synchronous and metachronous has been taken as 6 months.

RESULTS

During the period of five years, twenty-three patients presented with dual malignancy. Out of 23 cases, seven were synchronous (30.43%), and 16 were metachronous (69.56%). In the synchronous malignancy group, the most common site of first and second primary malignancy was breast [5 cases (71.4%) and 3 cases (42.8%), respectively]. In the metachronous malignancy group, the most common site of the first primary was breast (7 cases; 43.75%), followed by the head and neck (4 cases; 25%), and the most common site of the second primary was also the breast (6 cases; 37.5%), followed by the lung (5 cases; 31.25%).

CONCLUSION

Second primary malignancies are not rare and can occur at any age. Regular follow-up and screening procedures by the treating oncologist can play a major role in early detection followed by appropriate treatment of second primary tumors.

Prognosis of primary or metachronous prostate cancer in multiple primary genitourinary cancers; a single center experience with long-term results

OBJECTIVE

This study aims to analyze the challenges, approaches and long-term results of primary or metachronous prostate cancer (PCa) in cases with multiple primary genitourinary cancers.

METHODOLOGY

A total of 17 patients were included in the study. Patients with multiple primary genitourinary cancers were divided into two groups according to the diagnosis of primary or metachronous PCa as group 1 and group 2.

RESULTS

The median age of patients was similar in both groups. The median smoking status (pack-years) was higher in group 2 than group 1. The median prostate-specific antigen (PSA) level was higher in group 1 than group 2. The median follow-up time from primary to the metachronous tumour was higher in group 1 than group 2. The rate of recurrence in PCa was higher in group 1 than group 2. No statistically significant difference was observed in terms of patients' age, smoking status, PSA levels at diagnosis of PCa and biochemical recurrence or metastasis between the two groups (p > 0.05).

CONCLUSION

Primary PCa cases may progress more aggressively than metachronous PCa cases. Biochemical recurrence and metastasis may be less threatening in metachronous PCa cases than primary cases. Therefore, aggressive treatment can be avoided for metachronous PCa cases.

Rare case of uterine neoplasm: cervical sarcoma with endometrial carcinoma

Multiple primary malignant tumors (MPMTs) refer to two or more primary malignant neoplasms that simultaneously or successively occur in one or more organs in the same individual. Cervical sarcoma concomitant with endometrial carcinoma is rare. A 46-year-old woman was admitted because of increased menstrual volume for 4 years and irregular vaginal bleeding with discharge for 6 months. The diagnosis of endometrial carcinoma at stage II was made on the basis of results of ultrasound, pelvic magnetic resonance imaging, and hysteroscopic curettage. Extensive total abdominal hysterectomy + bilateral adnexectomy + bilateral ovarian arteriovenous high ligation + pelvic adhesion separation + pelvic lymphadenectomy +abdominal aortic lymphadenectomy via the abdomen were performed. Postoperative diagnosis of cervical sarcomas with endometrial carcinoma in stage IIIC1 was made according to the results of pathology and immunohistochemistry. Six cycles of cisplatin-epirubicin-isocyclophosphamide treatment were provided after the operation. Most clinical manifestations of cervical sarcomas are abnormal vaginal bleeding. Use of preoperative imaging and hysteroscopy is difficult for diagnosing cervical sarcomas, and postoperative pathological examinations and immunohistochemical diagnosis are mainly used instead. The possibility of MPMTs should be considered for endometrial carcinoma, especially if the cervical lesion is larger than that of the uterine cavity.

The Conundrum of Dual Primary Malignancies: Four Years’ Experience of a Single Tertiary Care Institute in India

Background: Encountering more than one malignancy in a cancer patient is no longer uncommon; this increasing incidence is mostly attributable to the improvements in life expectancy, awareness, and diagnostic facilities. This article aims to highlight this institute’s experience in diagnosis and treatment of patients of multiple primary malignancies and a comprehensive review of literature. Materials and Methods: This is a descriptive study of retrospectively collected data of a single institution over 4 years from 2013 to 2016. Known cases of cancer who were diagnosed with a second primary malignancy were included in the study. Various details such as age, sex, site of disease, temporal relation of two cancers (synchronous or metachronous), family history, tobacco use, treatment given, and survival at 1 year were recorded, organized in a tabular form, analyzed, and described. Results: A total of 29 cases of dual malignancies comprising 0.74% of a total of 3879 patients of cancer were encountered. Seventy-two percent of the cases were metachronous and 5 years was the mean time interval between tumors. There was a female preponderance, and the average age was 56 years. Breast was the most common site of malignancy. At 1 year from diagnosis of second primary, 69% of the patients were alive and 27% were disease-free. Conclusion: Second primary in a patient of cancer is becoming increasingly common and the suspicion of the same should always be borne in mind during follow-up. Prognosis as well as intent of treatment depends on respective stages of the two malignancies.

An elderly female patient with ROS1 rearrangement primary lung adenocarcinoma and breast carcinoma: a rare case report and review of the literature

We report the case of a 90-year-old female patient who was suffering from c-ros oncogene 1 (ros-1) rearrangement adenocarcinoma and breast cancer. After about 14 months of a reduced dose of crizotinib treatment, she had a stable disease according to the Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1). This patient’s case demonstrates that ros-1 rearrangements are not limited to patients of young age. In addition, this case indicates that crizotinib, as second-line, or even first-line, treatment may be effective and manageable in elderly patients. Furthermore, for elderly patients carrying a ros1 fusion, a reduced dose of crizotinib may be efficacious rather than a resistance factor. Based on our findings, we recommend that elderly patients with advanced lung adenocarcinoma should be considered for inclusion in molecular screening for ros-1 translocation, especially for never-smokers negative for epidermal growth factor receptor (egfr) mutation and the fusion between echinoderm microtubule associated protein-like 4 (EML4) and anaplastic lymphoma kinase (ALK). This deserves attention because the population is aging, with increasing incidence and morbidity of multiple primary malignant tumors. Neglect of breast nodules at the onset is one of the limitations of our case, as combination of primary lung cancer with breast cancer is common. Above all, use of antiestrogens before and after the diagnosis of non-small-cell lung cancer is related to a reduced risk of lung cancer mortality. Therefore, careful attention should always be paid to these cases.

Every distant deposit is not a metastasis: Synchronous primaries do exist

BACKGROUND

Synchronous occurrence of two malignant tumors is a rare event. With increasing use of sophisticated imaging modalities for staging, synchronous multiple tumors are more commonly detected now. Assuming the second primary malignancy as metastasis will change the intent of treatment from curative to palliative, greater awareness among oncologists is of paramount importance. This study is an example where thorough clinical examination and proper judgment resulted in correct diagnosis and appropriate treatment.

MATERIALS AND METHODS

This is a prospective descriptive study. Patients diagnosed with synchronous primary tumors from January 2016 to November 2017 at our center were reviewed.

RESULTS

Ten cases of synchronous primary malignancies were detected during this period. A total of 20 primary tumors were diagnosed. Lung carcinoma and gastrointestinal malignancies were the most common (five patients each). The median age was 59.5 years. Seven patients were male. Second primary tumor was suspected in four patients during clinical examination, while in six patients it was suspected on imaging. Even in the presence of two primary tumors, three patients were treated with curative intent.

CONCLUSION

Possibility of synchronous second primary malignancy should always be kept whenever a distant deposit is detected at an unusual site. Histopathological evaluation of the lesion before assuming a metastasis will lead to accurate diagnosis, staging, and appropriate treatment.

An observational study on the clinical features of esophageal cancer followed by multiple primary cancers

AIM

To investigate the nature of multiple primary cancers initiated by esophageal cancer-multiple primary cancers (EC-MPC).

PATIENTS & METHODS

SEER data about patients'/tumor characteristics, and survival were analyzed and compared.

RESULTS & CONCLUSION

1727 of 29,733 registered EC patients have EC-MPC. Individuals diagnosed at 60-79 years old, earlier stage and/or moderately differentiated EC were more likely to get EC-MPC. Fewer patients in the EC-MPC group suffered from metastases. Patients in the EC-MPC group showed a longer survival rate and lower EC-specific deaths. Other factors like age, sex, race, tumor differentiation and Tumor, Node, Metastasis stage also affected survival. Radiation can improve survival. EC-MPC patients have some distinct features compared with solitary EC.

Clinical Characteristics and Prognosis Associated with Multiple Primary Cancers in Breast Cancer Patients

Purpose

Breast cancer is one of the most common malignancies worldwide and the second most common cancer among Korean women. The prognosis of breast cancer is poor in patients with other primary cancers. However, there have been few clinical studies regarding this issue. Therefore, we analyzed the characteristics and prognosis of patients with breast cancer with multiple primary cancers (MPCs).

Methods

Data from the Korean Breast Cancer Society Registry were analyzed. Data from enrolled patients who underwent surgery for breast cancer were analyzed for differences in prognosis dependent on the presence of MPCs, and which MPC characteristics affected their prognosis.

Results

Among the 41,841 patients analyzed, 913 patients were found to have MPCs, accounting for 950 total MPCs. There was a significant difference in survival rates between the breast cancer only group and the MPC group. The 5-year survival rates were 93.6% and 86.7% and the 10-year survival rates were 87.5% and 70.4%, respectively. Among the 913 patients with MPCs, patients with two or more MPCs had significantly worse prognoses than patients with a single MPC. With respect to the time interval between breast cancer and MPC occurrence, patients with a 5-year or greater interval had significantly better prognoses than patients with less than 1 year between occurrences. Among MPCs, thyroid cancer was the most common primary cancer. However, this type was not related to the prognosis of breast cancer. Gynecologic cancer, colorectal cancer, upper gastrointestinal cancer, and lung cancer were related to breast cancer prognosis.

Conclusion

MPCs were a poor prognostic factor for patients with breast cancer. Two or more MPCs and a shorter time interval between occurrences were worse prognostic factors. Although MPCs were a poor prognostic factor, thyroid cancer did not affect the prognosis of patients with breast cancer.

The clinicopathological features of second primary cancer in patients with prior breast cancer

Nowadays, the risk of developing second primary cancers among women diagnosed with prior breast cancer represents a public health issue worldwide.Twenty-eight cases of the primary breast cancer with the multiple primary cancers (MPC) between 2008 and 2015 at our hospital were retrospectively analyzed in regards to age of patients, family history, interval time of the 2 cancers, and survival time of these patients.A total 28 cases were analyzed, at the mean age of 44.57 years at the diagnosis of the first primary cancer. The most common primary cancer in these breast cancer patients was contralateral breast cancer. Of 28 patients with breast cancer, 16 developed a second malignant tumor of the opposite breast, there were no significant difference both median age at first breast cancer and second breast cancer (P > .05). The difference of interval time of 2 cancers also had no statistical significance. There was no statistically significant difference in overall survival between the bilateral primary breast cancers (BPBC) group and the group of breast cancer patients who diagnosed with another cancer (P > .05). If we grouped patients age of diagnosed with the first cancer (<45, ≥45 years), no statistical different between 2 groups (P > .05). However, the survival time with positive-node patients was lower than in patients with node-negative, the difference had a notable significant difference (P < .01). And there are 3 cases had a positive family history for malignant tumor in the form of first-degree relative.Multiple primary carcinoma in patients with prior breast cancer is not the influencing factor of prognosis. It is crucial to detect, diagnose, and treat cancers at their early stage for improving the cure rate of cancer and the survival rate of patients.

Second primary cancers in patients with urothelial cancers

Purpose

To investigate the second primary cancers (SPCs) in patients with urothelial cancer (UC).

Materials and Methods

The records of 2,339 patients whose UC was diagnosed between January 1974 and December 2012 were reviewed. All data about characteristics of patients, of UC and, of SPC was, recorded digitally. We investigated the prevalence and the type of second or higher order cancers, and the factors associated with SPC.

Results

Total 260 patients (11.1%) had SPC, 14 had a third primary cancer and one had a fourth primary cancer. The most common SPC with UC was lung cancer (29.6%). Of all 260 with SPC, 64 (24.6%) had synchronous (within the 6 months) SPC, 120 (46.2%) had subsequent SPC and, 76 (29.2%) had antecedent SPC. The mean duration of SPC was 56 months in patients with subsequent SPC and 75.8 months in patients with antecedent SPC. The mean age at the time of diagnosis of UC was higher in patients with SPC. The ratio of male gender, body mass index, blood type, status of smoking and, occupational risk was similar in both groups. Total amount of smoking and the mean follow-up were higher in patients with SPC.

Conclusions

The majority of the patients with UC have long life expectancy. In patients with UC, the risk of having another cancer is quite higher than normal population. The physicians managing patients with UC should look for SPC.

Influence of residential environment and lifestyle on multiple primary malignancies in Taiwan

BACKGROUND

Multiple primary malignancies (MPM) have become increasingly prevalent worldwide. This investigation was aimed at establishing the clinicopathological characteristics of MPM patients and evaluating the impact of the living environment on MPM in the Taiwanese population.

MATERIALS AND METHODS

From January 2009 to December 2013, a total of 8,268 cancer patients were identified in our institutional center. Of these, 125 were diagnosed as MPM and thus enrolled. Data for clinicopathological features and treatment approaches for these MPM patients living in urban or suburb zone were obtained. Findings for the air pollution status in Taiwan were also collected.

RESULTS

The most common cancer match of MPM was esophageal cancer with hypopharyngeal cancer (12.8%), followed by colorectal cancer with gastric cancer (6.4%) and colorectal cancer with breast cancer (5.6%). The air quality was significantly worse in the urban than in the suburban zone and there was a remarkably higher portion of MPM patients in the urban zone suffering from grade III and IV post-chemotherapeutic neutropenia (30.8% vs 15.1%, P=0.036).

CONCLUSIONS

The tumor frequency and site distribution should be taken into the clinical evaluation because there is a relatively high risk of developing MPM. This study also highlighted the potential influence of environmental factors on post-chemotherapeutic neutropenia for patients with MPM.

Multiple primary malignancies involving lung cancer

Background

The incidence of multiple primary malignancies (MPM) has increased sharply in recent decades. However, the clinical characteristics and prognosis of MPM patients involving lung cancer were not fully elucidated. This retrospective study was designed to explore the clinical characteristics and prognosis of MPM patients involving lung cancer in the People’s Republic of China.

Methods

Of 5405 lung cancer cases diagnosed at the Guangdong Lung Cancer Institute between 2005 and 2013, we analyzed 185 patients (3.4 %) with MPM involving lung cancer.

Results

Among 185 patients with MPM involving lung cancer, 10 (5.4 %)had three malignancies and 175 (94.6 %) had two malignancies. 10 patients with three malignancies were excluded from the analysis to avoid misunderstanding. Of 175 accompanying malignancies, 64 (36.6 %) were synchronous MPM patients and 111 (63.4 %) were metachronous MPM patients; 49 (28.0 %) were lung cancer first MPM patients and 126 (72.0 %) were other cancer first MPM patients. The most frequent accompanying malignancy was colon cancer (25/175), followed by rectal cancer (18/175), esophageal cancer (17/175), and thyroid cancer (13/175). Metachronous MPM patients showed significantly better overall survival (OS) than synchronous MPM, with a median OS of 72.8 (range 12.2–391.0) and 12.9 (range 0.8–86.3)months, respectively (P < 0.001). Cox regression analysis revealed that time of occurrence and stage were independent factors for OS.

Conclusions

Colorectal cancer, esophageal cancer, and thyroid cancer were the tumors that most frequently accompanying lung cancer. Metachronous MPM patients showed significantly better OS compared with synchronous MPM patients.

Clinical features of patients with esophageal and second primary cancers

BACKGROUND

The prevalence of esophageal cancer (EC) with second primary cancers (SPC) is increasing worldwide. This study was aimed to understand the clinical features of EC patients with SPC in the Taiwanese population.

MATERIALS AND METHODS

Clinical and laboratory data for 180 EC patients with or without SPC were collected between January 2009 and December 2013. Information on treatment approaches, location of SPCs and ABO blood type were also collected and stratified.

RESULTS

The most common SPC in EC patients was hypopharyngeal cancer, followed by laryngeal cancer and hepatocellular carcinoma in our study. Malignancies of colon, prostate and lung were also found. There was a significant higher portion of blood type A in the EC patients with SPC compared with those without (42.4% vs 19.5%, P=0.006).

CONCLUSIONS

The frequency and SPC site distribution and blood type A should be considered in clinical evaluation of EC patients with a high risk of developing SPC in the Taiwanese population.

Multidisciplinary treatment based on surgery leading to long-term survival of a patient with multiple asynchronous rare primary malignant neoplasms: A case report and literature review

Patients that present with multiple primary malignant neoplasms are increasingly encountered, but the treatment of such patients presents specific challenges and long-term survival is rare. The present study reports the case of a 45-year-old female diagnosed with three rare, distinct primary malignant neoplasms, including epithelioid hemangioendothelioma (EHE) of the brain, Ewing’s sarcoma of the lumbar 2 vertebra and a malignant solitary fibrous tumour (SFT) of the liver, at different time points. The patient underwent multidisciplinary treatment according to the diagnoses, including radial resection of all primary lesions, chemotherapy (consisting of vincristine, dactinomycin, cyclophosphamide and adriamycin) and radiotherapy, to treat Ewing’s sarcoma and metastases of EHE and malignant SFT. Following these treatments, the patient survived for >14 years. Multidisciplinary treatment regimens based on surgery can lead to long-term survival of patients with multiple asynchronous rare primary malignant neoplasms. The present study reported that multidisciplinary treatment regimens based on surgery can lead to the long-term survival of patients with multiple asynchronous rare primary malignant neoplasms.

Clinical features of multiple primary malignancies: a retrospective analysis of 72 Chinese patients

There is a scarcity of reports addressing patients with multiple primary malignancies (MPM), especially for Chinese cses. The aim of this study was to present a detailed analysis of Chinese patients presenting with at least two primary malignancies. Particularly, the clinical characteristics and survival between synchronous and metachronous MPM were compared. Out of 6,545 cases, 72 patients (1.1%) including 39 males (54.2%) and 33 females (45.8%) were diagnosed as MPM, giving a male: female sex ratio of 1.2:1. Of these, there were 16 (22.2%) cases of synchronous MPM (7 males, 9 females), 55(76.4%) metachronous (31 males, 24 females), and 1 "mixed form". For first tumor diagnosis time, synchronous MPM patients generally presented later than the metachronous cases. The top three sites for malignancies with metachronous MPM were colorectum, head and neck, and lung, while for synchronous they were lung, colorectum and breast. Among MPM patients, the median survival time was 15.7 years and the 5-year survival was 56%, and there was statistical difference in MPM categories (P < 0.05). The median survival time was 17.3 years and 3.8 years for metachronous and synchronous MPM patients, respectively. In comparison with synchronous MPM patients, those metachronous had a longer survival. This studies increase understanding of the clinical features of Chinese MPM patients and suggest that those presenting with metachronous cancers have a higher incidence and a better prognosis.

Multiple neoplasms, single primaries, and patient survival

Background

Multiple primary neoplasms in surviving cancer patients are relatively common, with an increasing incidence. Their impact on survival has not been clearly defined.

Methods

This was a retrospective review of clinical data for all consecutive patients with histologically confirmed cancer, with emphasis on single versus multiple primary neoplasms. Second primaries discovered at the workup of the index (first) primary were termed simultaneous, if discovered within 6 months of the index primary were called synchronous, and if discovered after 6 months were termed metachronous.

Results

Between 2005 and 2012, of 1,873 cancer patients, 322 developed second malignancies; these included two primaries (n=284), and three or more primaries (n=38). Forty-seven patients had synchronous primaries and 275 had metachronous primaries. Patients with multiple primaries were predominantly of Caucasian ancestry (91.0%), with a tendency to develop thrombosis (20.2%), had a strong family history of similar cancer (22.3%), and usually presented with earlier stage 0 through stage II disease (78.9%). When compared with 1,551 patients with a single primary, these figures were 8.9%, 15.6%, 18.3%, and 50.9%, respectively (P≤0.001). Five-year survival rates were higher for metachronous cancers (95%) than for synchronous primaries (59%) and single primaries (59%). The worst survival rate was for simultaneous concomitant multiple primaries, being a median of 1.9 years. The best survival was for patients with three or more primaries (median 10.9 years) and was similar to the expected survival for the age-matched and sex-matched general population (P=0.06991).

Conclusion

Patients with multiple primaries are usually of Caucasian ancestry, have less aggressive malignancies, present at earlier stages, frequently have a strong family history of similar cancer, and their cancers tend to have indolent clinical behavior with longer survival rates, possibly related to genetic predisposition.

Tumor necrosis factor-alpha gene promoter -308 and -238 polymorphisms in patients with lung cancer as a second primary tumor

Background

Lung cancer is the most common second primary cancer. We investigated whether the TNF-α-308 and TNF-α-238 polymorphisms were associated with the susceptibility and severity of lung cancer as the second primary cancer (LC2).

Material/Methods

This study included 104 patients from the group LC2. The control subjects included 2 groups. The first control group (LC1) comprised 201 unrelated patients with lung cancer as a first primary cancer. The second control group (HC) comprised 230 healthy blood donors, matched for sex and age to the study group.

Results

The frequencies of the TNF-α-238 polymorphism GG genotype and the G allele were higher in the LC2 group than in the LC1 group, but the differences did not reach significance (p=0.054 and p=0.057, respectively). Similar differences were found in the TNF-α-238 polymorphism GG genotype and G allele between the LC2 group and the HC group (p=0.054 and p=0.057, respectively). In terms of the different types of lung cancer, patients with a second primary NSCLC (non-small cell lung cancer) more frequently had TNF-α-238 polymorphism GG genotypes and G alleles than patients with a first primary NSCLC (the differences approached statistical significance: p=0.060, p=0.064, respectively). All (100%) patients of group LC2 (n=104) had the GG genotype and the G allele. GG genotype was exclusive and no A allele was found in group LC2.

Conclusions

TNF-α-238 polymorphism GG genotype and the G allele could have a promotional effect on the development of NSCLC in the group of patients with LC2.
