Tuberculosis Coexistence in Pediatric Hodgkin’s Lymphoma: A Tropical Country Experience
Abstract
Introduction Hodgkin’s lymphoma (HL), being one of the common cancers among children, may occasionally masquerade as an infectious illness. Similarly, an underlying infection like tuberculosis (TB) may be missed in cases of HL because of similarity in clinical and radiological features. Here, we present our data of association of HL with histopathologically proven TB lymph node, their clinical presentation, treatment details, and outcome.
Materials and Methods A retrospective review of all the cases of HL diagnosed between January 2007 and December 2016 was done. The cases which had an association of TB, based on the histopathology, were reviewed separately.
Results A total of 262 children with HL were treated at our institute from January 2007 to December 2016. Of these cases, 42 children had received empirical antitubercular therapy (ATT) (due to suspicion of TB) before presenting to us, and only five cases had histopathologically proven TB lymph node. Ziehl–Neelsen (ZN) stain for acid-fast bacilli (AFB) was positive in the biopsy specimen of all the five cases, proving TB lymph node coexistence with HL. They were treated with six-drug ATT as per the Revised National Tuberculosis Control Program (RNTCP) guidelines along with chemotherapy with adriamycin, bleomycin, vinblastine, and dacarbazine regimen. All the five patients are healthy and disease free until their last follow-up.
Conclusion A high-end suspicion for concomitant TB and HL is needed, especially in our country where TB is still rampant. Biopsy with immunohistochemistry and demonstration of AFB can enable a definite diagnosis of both the entities.

Introduction
Lymphoma is the third most common cancer among children (aged 14 years or younger) worldwide. There are mainly two broad categories of lymphoma, namely Hodgkin’s lymphoma (HL) and nonHodgkin’s lymphoma (NHL). Lymphomas may occasionally masquerade as an infectious illness.[1] Similarly, an underlying infection like tuberculosis (TB) may be missed in cases of lymphoma, especially HL, because of similarity in clinical and radiological features.[2] Cell-mediated immunodeficiency is well known in HL, which may result in infections such as TB, especially in developing countries like India where TB is still a major concern and is widely prevalent.[3] [4] Here, we present data from a tertiary care cancer center in South India on children who had an association of HL with histopathologically proven TB, their clinical presentation, treatment details, and outcome.
#
Materials and Methods
A retrospective review of all the cases of HL diagnosed between January 2007 and December 2016 was done. All the data were obtained from the patients’ hospital case records for analysis. The cases which had an association of TB were reviewed separately. Those patients who had already received empirical antitubercular therapy (ATT) before presenting to us were excluded from the study, as there was no evidence to support the presence of TB. Only those patients who had histopathologically proven TB during the diagnosis of HL were included in this study. Demographic features such as age, sex, and socioeconomic status were noted. A detailed family history was taken in each case, including a history of contact with TB. Duration of symptoms was recorded from the time of onset to the time of presentation to the hospital. The presence of TB symptoms was defined as fever, loss of 10% or more of weight in the past 6 months, and drenching night sweats. All patients were examined clinically to look for the involvement of the different nodal groups such as cervical, axillary, mediastinal, inguinal, abdominal, and of the spleen. Bulky disease was defined as the size of lymph nodal mass > 6 cm or mediastinal mass size more than one-third of the maximal thoracic diameter on chest X-ray.[5] The WHO charts were used for anthropometry.[6] Diagnosis of HL was confirmed by histopathologic examination of lymph node biopsy and immunohistochemistry. The WHO system was used for pathologic classification.[7] Staging investigations included baseline chest X-ray, ultrasound abdomen, and CT of neck, chest, abdomen, and pelvis. The Ann Arbor staging system was used to stage the patients.[8] Koch’s workup included Mantoux test and chest X-ray. TB lymph node was diagnosed in these cases of HL, based on the demonstration of acid-fast bacilli (AFB) in the biopsy specimens.
The chemotherapy regimen used at our institute during the study period was adriamycin, bleomycin, vinblastine, and dacarbazine (ABVD). Chemotherapy was initiated after 2 weeks of starting ATT. All patients received six cycles of ABVD as per the institution protocol. Response was assessed after each cycle clinically and radiologically after the completion of six cycles. End-of-therapy response assessment included either positron emission tomography (PET) CT or contrast-enhanced CT, depending on affordability. Complete remission (CR) was defined as complete disappearance of all clinical and radiologic evidence of disease. Partial remission (PR) was defined as a reduction of > 50% of the tumor area (the product of the two greatest diameters) but less than a CR. The appearance of a new lesion or a 25% increase in an existing lesion was considered progressive disease (PD). All other responses were considered stable disease (SD).[9] Radiotherapy was given to those who achieved PR and those who had bulky disease at presentation. External beam radiation therapy (EBRT)/involving field radiation therapy (IFRT) was used to deliver RT at a dose of 20 to 36 Gy. ATT as per the Revised National Tuberculosis Control Program (RNTCP) guidelines was initiated for those testing positive for TB adenitis.[10] ATT was given along with the chemotherapy as per the schedule. The toxicity profile was retrieved from the patient files. After the completion of treatment, they were followed-up monthly in the 1st year, 2 monthly in the 2nd year, 3 monthly in the 3rd and 4th years, and 6 monthly in the 5th year.

Results
A total of 262 children with HL were treated at our institute from January 2007 to December 2016. Of these cases, 42 children had received empirical ATT (due to suspicion of TB) before presenting to us, and only five cases had histopathologically proven TB lymph node. The case details are presented in [Table 1]. The median age at diagnosis was 11 years (range: 5–13 years). A male sex preponderance was noted (male:female = 4:1). All the children belonged to lower class as per BG Prasad socioeconomic status classification.[11] The median duration of symptoms was 8 months (range: 5–24 months). TB symptoms (fever and weight loss) were present in three of them. The major group of lymph node in all the children was the cervical group. All five of them had concomitant cervical tubercular lymphadenitis and none had evidence of pulmonary/extrapulmonary TB. One child had a history of contact with TB. However, none of them were treated for TB before presenting to us. Three of them had bulky cervical node disease and two presented with multiple discrete lymph nodes. The other groups of lymph nodes involved were the retroperitoneal group in one child and axillary and inguinal group in the other. The remainder did not have any other group of lymph node involvement. Three of them had splenomegaly, with two of them demonstrating hypoechoic lesions on ultrasonography. The final staging of each case is shown in [Table 1]. Cervical group of lymph nodes was biopsied in all of them. Nodular sclerosis was the histologic subtype in three of them and two had mixed cellularity subtype. Ziehl–Neelsen (ZN) stain for AFB was positive in the biopsy specimen of all the five cases, proving TB lymph node coexistence with HL.
They were treated with six-drug ATT with 2 months of isoniazid, rifampicin, pyrazinamide, and ethambutol followed by 4 months of isoniazid and rifampicin as per the RNTCP guidelines. Chemotherapy with ABVD regimen was initiated at least 2 weeks after starting ATT. All received six cycles of ABVD followed by clinical and radiological response assessment. Two of them attained CR, whereas three of them with bulky disease at presentation attained PR and hence required RT. There were no significant delays in chemotherapy. The median duration of each ABVD cycle was 14 days (range: 14–28 days). Chemotherapy delay was present in two children, one of whom had delay in two cycles, whereas the other had delay in three cycles. Cause of delay in both cases was found to be prolonged neutropenia. The toxicity profile is described in [Table 2]. No significant toxicity attributable to the addition of ATT drugs to ABVD regimen was noted. All the five patients are healthy and disease-free till their last follow-up.

Discussion
HL is one of the most common malignancies of childhood involving lymph nodes and extranodal sites. Cell-mediated immunodeficiency is a well-known entity associated with HL. This may predispose children with HL to many infections. In India, TB, being one of the common diseases with an annual risk of infection between 2% and 5% in young individuals, can affect these children.[4] TB can precede or can occur concomitantly with the diagnosis of HL. It can also occur during or after the treatment of HL. Concomitant TB with HL can create a confusion in the diagnosis because of similarities in their clinical, radiological, and pathological presentation. Similarly, TB occurring during or after the treatment of HL can pose difficulty in differentiating resistant or relapsed disease. In this study, we looked at our patients who had concomitant TB with HL at diagnosis.
Cell-mediated immunity plays an important role in the control of mycobacterial infections. T-cells produce a variety of cytokines which are capable of activating macrophage bacterial activities. In malignancy, this cell-mediated immunity is affected, leading to the spread of the infection and cause symptomatic disease.[12] Many a times, TB in these patients would be in advanced stage before it could be diagnosed.
The distinction between TB and HL can be quite challenging. Both present with similar symptoms such as fever, cough, fatiguability, night sweating, and weight loss. Mantoux test can be negative in HL patients in spite of active TB due to impaired cell-mediated immunity.[13] Chest X-ray and CT are the basic imaging modalities but might not categorically differentiate the two. Newer modalities such as single positron emission CT or/and PET imaging also do not aid in establishing the diagnosis, as hypermetabolic lesions are not specific for malignancy.[14] Biopsy remains the most specific and sensitive diagnostic procedure. The findings of caseating or necrotizing granulomatous lesions typical for TB can also be found in HL and NHL.[15] Reed–Sternberg cells (R–S cells) are not entirely specific for HL. The expression of CD15 and CD30 antigens on R–S cells is necessary for the diagnosis of classical HL ([Fig. 1]). Similarly, the presence of AFB in biopsy and/or culture is required for the confirmation of TB ([Fig. 2]). A total of five patients had histologically proven HL with concomitant TB lymph node (AFB positive on ZN stain) at our center among those analyzed in the study period.

A large Indian study from Chennai by Radhakrishnan et al comprised 172 patients with HL. Although 32 of them had received empirical ATT before the diagnosis of HL, none had evidence of active TB at diagnosis.[16] In our cohort, 42 had received empirical ATT, while only five had active TB at diagnosis. Karakas et al studied the association of pulmonary TB, specifically with HL.[17] In this study, 14 among 70 children diagnosed in the study period had pulmonary TB, and only two of them had concomitant HL and TB at the time of diagnosis, seven of them developed TB during treatment, and two of them after the cessation of treatment.
TB associated with malignancy can present with atypical features too involving extrapulmonary sites.[18] Codrich et al described TB associated with primary pulmonary Hodgkin’s disease.[19] Several reports have described the coexistence of TB and NHL in lymph nodes. It has been reported that the risk of NHL is significantly increased (odds ratio: 1.8) in individuals with a history of TB.[20]

Conclusion
A high-end suspicion for concomitant TB and HD is needed, especially in our country where TB is still rampant. The difficulty in differentiating the two can sometimes cause delay in the diagnosis and hence the treatment. Biopsy with immunohistochemistry and demonstration of AFB can enable a definite diagnosis in difficult cases.
