AIM OF STUDY: We analyzed the data of second primary malignancy (SPM) from one of the tertiary cancer centers of North India, and the basic aim was to retrieve incidence, prognosis, and outcomes. MATERIALS AND METHODS: A retrospective study was conducted in the Department of Radiation Oncology in a tertiary cancer center between January 1, 2011, and December 31, 2015. A total of 6000 cases of cancer were analyzed, out of which cases who presented with histological proven synchronous SPM were included in this study. RESULTS: The present study showed three cases (8.1%) of SPM who are attributed to field carcinogenesis. There were five cases in which metachronous malignancy develops in the previous radiation therapy field. There is 26% of synchronous malignancy as compared to 74% of metachronous malignancy. In the present study, most diagnosed synchronous malignancies were carcinoma breast, while in metachronous malignancies, carcinoma breast and gynecological cancers were most common. CONCLUSIONS: SPMs are not very rare. Hence, pretreatment and follow-up evaluation should be meticulous to rule out SPMs.

 » Introduction Top


The incidence of double malignancy is not uncommon.[1],[2],[3] Bugher in 1934 analyzed cases of double primary malignancies and derived an equation for the probability of death during a specified period with a new second malignancy.[4]

The second primary malignancy (SPM) is defined as a second de novo malignant neoplasm with known cancer. An SPM can be synchronous or metachronous. Warren and Gates first gave the criteria used for the diagnosis of SPM.

Warren and Gates criteria for diagnosis of multiple primary malignancies are as follows.[5]

  1. Each of the tumors must be malignant, each confirmed by histology
  2. Each must be geographically separate and distinct. The lesions should be separated by normal mucosa
  3. Probability of one being the metastasis of the other must be excluded.


An SPM can be synchronous or metachronous. When the SPM is diagnosed within 6 months of the primary tumor, it is known as synchronous malignancy and the term metachronous is used when the SPM is diagnosed more than 6 months after the diagnosis of the primary tumor.[6] In literature, data regarding the occurrence and the outcome of SPM from the Indian subcontinent are limited. Hence, we present the data of SPM from one of the tertiary cancer centers from North India with a review of relevant literature.


 » Materials and Methods Top


We conducted a retrospective observational study in the Department of Radiation Oncology in a tertiary cancer center between January 1, 2011, and December 31, 2015. A total of 6000 cases of cancer were analyzed, out of which cases who presented with histological proven synchronous and metachronous primary as per the Warren and Gates criteria were included in the study. Time interval which was taken to differentiate between synchronous and metachronous malignancies was 6 months.[7],[8],[9] Details such as age of diagnosis of each tumor, sex, any family history, site of origin, histopathological and radiological imaging, whether the tumor was synchronous or metachronous, clinical staging, treatment received by patient, and status at last follow-up were recorded.


 » Results Top


During a period of 5 years between January 1, 2011, and December 31, 2015, total of 6000 patients were registered, out of which 38 patients presented either with metachronous malignancy or with synchronous malignancy. In the present study, one patient presented with synchronous malignancy (carcinoma breast and urinary bladder cancer) and developed carcinoma cervix IIB after 7 years at as metachronous malignancy.

The most common site of primary malignancy is carcinoma breast (11 cases), followed by head and neck squamous cell carcinoma (HNSCC) (10 cases) [Figure 1] and [Figure 2].

Synchronous malignancy

A total of ten cases were diagnosed with synchronous malignancy. Out of these ten cases of synchronous malignancy, five were male and five were female. Median age of diagnosis was 58 years (range, 28–85 years) [Table 1].

Metachronous malignancy

A total of 29 cases were diagnosed with metachronous malignancy. Male-female ratio is 0.75. The median age for the primary tumor was 52 years (range, 25–76 years) and that for the metachronous malignancy was 59 years (range, 27–80 years). The median time interval between the primary and secondary malignancy was 5.5 years (range, 1–16 years) [Table 2].

 » Discussion Top


The incidence of SPM is not uncommon; it is common for the last 100 years.[6] The etiopathology of SPM can either be various genetic events or common environmental risk factor.[3] SPMs have been associated with DNA microsatellite instability, for example, Lynch I and Lynch II syndromes.[10] Carcinoma of breast, esophagus, and soft tissue has been associate with mutation in tumor suppressor genes such as p16, p53, PTEN, and Rb gene.[11]

It has been found that the cumulative lifetime risk of SPM in HNSCC is 36%.[9] This has been attributed to field carcinogenesis in response to exposure to risk factors such as tobacco, smoking, and alcohol consumption.[9],[12] In our study, there are three cases (8.1%) in which SPM is attributed to field carcinogenesis. Another cause of SPM is ionizing radiation.[13] Various studies have shown that the risk of lung cancer, sarcoma increases with a radiation dose above 5 Gy. Such type of cancer usually occurs in the prior radiation field and usually after a latent period of ten or more years.[14],[15],[16] In the present study, there are five cases in which metachronous malignancy develops in the previous radiation therapy field [Table 3].

SPM can occur at any age. Various studies done so far revealed that it is more common in old age.[17],[18],[19],[20],[21] In the present study, the median age at the time of second tumor diagnosis is 59 years and 70% of patients with SPM were more than 50 years of age. In the reviewed literature, male/female ratio varies between 0.9 and 3.5, with male predominance.[20],[22],[23] In the present study, the male: female ratio is 0.85.

The ratio of synchronous to metachronous malignancies differs in different studies. In a study by Aydiner et al., synchronous malignancy was 34% as compared to metachronous malignancy which was 66%.[19] Flannery et al. reported 20% of synchronous and 80% of metachronous tumors in their SPM series.[24] In the present study, there are 26% of synchronous malignancy as compared to 74% of metachronous malignancy. Usually, synchronous SPMs are seen in genitourinary and gastrointestinal systems.[25],[26] In the present study, most diagnosed synchronous malignancies were carcinoma breast; in metachronous malignancies, carcinoma breast and gynecological cancers were most common.

As per the SEER data results (1973–2003), the most common primary cancers in patients with SPM are breast carcinoma, prostate carcinoma, respiratory system and lung cancers, colorectal cancer, and urinary system cancers.[27] In the present study, the most common primary tumors were carcinoma breast, HNSCC, gynecological cancers, gastrointestinal tract (GIT) malignancy In males, most common primary malignancies were HNSCC, GIT malignancy, and genitourinary malignancy and that in female were carcinoma breast and gynecological cancers. In other studies, most common tumors were carcinoma larynx, lung cancer, and breast cancer.[20],[22],[28]

The possibility of SPM must always be considered while pretreatment evaluation. For early detection of SPM, screening procedures are useful, and this in turn will improve the outcome of the patients with SPM. However, the optimal screening modalities and strategies to reduce mortality from SPM remain to be defined for most tumor sites.[29]


 » Conclusions Top


SPM is not uncommon. It manifests either as synchronous or metachronous malignancy. The early diagnosis of SPM should not be missed during follow-up. And also, during follow-up, cancer patients should be informed the role of preventive medicine and encourage use of screening methods.
