  Abstract 

Purpose: There is scarcity of data regarding clinical presentation and outcome of retinoblastoma patients in India. Objectives: The objective of this study was to assess the clinical profile of retinoblastoma patients in a tertiary care hospital in India from 1983 to 2013. Subjects and Methods: A retrospective analysis of clinical records of 141 patients with retinoblastoma registered from 1983 to 2013 at Government Medical College, Nagpur, India, was conducted. Demographics, clinical features, modes of treatment, and outcome of the patients were assessed. Results: Majority of patients (81 [57.45%]) presented in the age group of 1–3 years and were males. One hundred and fourteen patients (80.85%) had unilateral disease, while rare presentations of trilateral/quadrilateral retinoblastoma were also noted. Proptosis was seen in 81 (57.45%) patients as presenting symptom. Eighty-nine patients (63.12%) had locally invasive disease-involving sites. Forty-four patients (31.19%) developed distant metastasis. Surgical management and external beam radiotherapy were followed in majority of patients. Trend of increased usage of chemotherapy was seen from the mid-1990s. One hundred and twelve patients (79.43%) died with the disease. Conclusions: Data from this study show late diagnosis, leading to poor outcome for patients with advanced retinoblastoma, which is in accordance with data from other developing countries. Even though management of patients changed in accordance with changing standard of care over the decade, mortality remained high.

  Introduction Top


Retinoblastoma is the most frequent childhood intraocular tumor with a global incidence of 1:20,000 births.[1] Global incidence data for retinoblastoma show an approximate 50-fold variation, which is highly atypical for a pediatric tumor. Incidence of Retinoblastoma on a global scale is 11/ million children in 5 years and younger age group. In India, incidence rate stands at 0.6 cases per 100,000 children. Nagpur Cancer Registry reports a prevalence of 0.1/100,000 population. Management of retinoblastoma has changed during years with a survival rate of >95% in developed countries.[2],[3] However, in developing countries, cure rates of <50% are observed, primarily because of advanced disease at the time of diagnosis.[4],[5],[6] Data detailing the clinical presentation and treatment outcomes of retinoblastoma, especially in Indian settings, are scarce, and hence, this study was undertaken to assess the clinical profile of patients with retinoblastoma.


  Subjects and Methods Top


A retrospective cohort study was conducted by reviewing clinical records of all retinoblastoma patients (n = 141) registered from 1983 to 2013 at Government Medical College and Hospital, Nagpur, India. The Institutional Ethics Committee approval was obtained. The diagnosis of retinoblastoma was based on history and physical examination with complete ocular examination. Demographics, clinical presentation, follow-up examinations, and outcome of the patients were noted.


  Results Top


One hundred and sixty-two eyes in 141 patients were diagnosed with retinoblastoma. Numbers of patients recorded during the first decade (1982–1993), second decade (1994–2003), and third decade (2004–2013) were 72, 44, and 25, respectively. The mean follow-up of all patients was 112 days (0–791).

Clinical profile of the patients has been described in [Table 1]. [Figure 1] shows appreciable change in trends during the management of retinoblastoma patient over three decades.

  Discussion Top


Retinoblastoma is a rare disease of early childhood. Due to extremely low incidence, the features of retinoblastoma patients are not routinely assessed. In developing countries such as India, it is important to identify the clinical features on presentation and complications of these patients. Data from developed countries and urban treatment centers in India show leukocoria (white eye) as a leading presenting symptom (early diagnosis) along with excellent survival status with the highest level of quality of life. The present study shows data in sync with data from developing countries with respect to late diagnosis, advanced stage at presentation & poor outcomes/loss of follow up.[7],[8],[9],[10],[11] Presentation for late cases varies from proptosis to fungating mass with secondaries.[12] Presentation of proptosis in majority of cases can be attributed to the delay in seeking consultation by the patient.[13] Extraocular retinoblastoma is very rare in developed countries (2%–5%).[14] In developing nations, extraocular disease contributes to half of all retinoblastoma cases presenting to a tertiary care referral center, which is in accordance with the findings of this study.[15],[16]

Reese–Ellsworth grading, formulated in 1960, has been widely used to predict the outcome of retinoblastoma treated with external beam radiotherapy (EBRT); however, as chemotherapy gradually replaced radiotherapy, new staging system was developed to predict the outcome for eyes treated with chemotherapy and focal treatments, which were international intraocular retinoblastoma. Majority of cases presented in an advanced stage. These findings were in accordance with data from other developing nations.[7],[10],[11]

Surgical management and EBRT are considered standard treatment protocol for eyes with advanced stage. Resource deficiency, unavailability, and cost of drugs till 1990s precluded the use of chemotherapy in majority of patients in this study. However, with changing guidelines and availability of standard drugs, number of patients receiving chemotherapy increased appreciably, coinciding with decrease in patient being treated with surgery and EBRT, which has been observed in [Figure 1].

EBRT was the only alternative to enucleation until the mid-1990s and is still an option to treat large tumors.[17] Scarce supply of ketamine till 1990s as anesthetic agent used for immobilizing pediatric patients before radiation therapy session prompted use of hypofractionated RT, which enabled treatment to be completed in less duration. Dose prescribed in patients treated with radical intent was 36 gy/9 fractions in 2–3 weeks, which was equivalent to conventional 50 Gy/5 times per week fractionation.[18]

Treatment abandonment as well as loss to follow-up has also been reported from other developing countries,[10],[19],[20] which could be attributed to no response/progressive disease in an advanced stage, inability to accept enucleation as form of treatment, inability to cope up with frequency of follow-up, illiteracy, poverty, and negligence.

To unearth grim situation, specifically in India, as per one retinoblastoma world statistical analysis, China recorded 1095 retinoblastoma patients in 2013 in 28 established Retinoblastoma Treatment Centers (RTB), while Pakistan showed 312 patients in 6 RTBs, while in India, 1730 patients took treatment in 11 RTBs. Various approaches for improvement in the management of retinoblastoma in developing countries[19] have been summarized in [Figure 2].

  Conclusions Top


Data from this study show late diagnosis, leading to poor outcome for patients with advanced retinoblastoma, which is in accordance with data from other developing countries. Even though management of patients changed in accordance with changing standard of care over the decade, mortality remained high. Inequality in patient access to health care is the reality in India. This study underlines this well-known fact and brings forth strategies which can lead to improvement of this scenario.
