For patients with leukaemia, aplastic anaemia, lymphoma, myelodysplastic syndrome, thalassaemia, or sickle cell disease who have been told that bone marrow transplant is the next step in their treatment, the question of which centre to choose carries extraordinary weight. The centre must have the clinical depth to perform the transplant, the institutional infrastructure to manage the infection risks during the critical neutropenic period, the post-transplant monitoring to detect and treat rejection and graft-versus-host disease, and the international patient services to support families who have traveled from abroad through what can be a fifty to sixty-day in-country stay. SIMS Hospital, Vadapalani, Chennai the Sri Ramaswamy Memorial Institute of Medical Sciences offers bone marrow transplant as a confirmed clinical service within its multi-organ transplant programme, supported by a haematology department, NABH and NABL accreditation, dedicated international patient services, and the same integrated infrastructure that has made SIMS one of Chennai's most recognised tertiary care hospitals for international patients from Bangladesh, the Gulf, Sri Lanka, and East Africa.
SIMS Hospital, Chennai: The Institutional Foundation
SIMS Hospital, Vadapalani is a multi-specialty tertiary care hospital located on Jawaharlal Nehru Salai, Vadapalani, Chennai. Established in 2014, it has grown into one of Chennai's most comprehensive tertiary care centres, recognised with multiple institutional awards including the Best Multi-Speciality Hospital in Chennai and the Best Hospital for Neuro Care in Chennai from the Honourable Minister for Health and Family Welfare, Government of Tamil Nadu, and top rankings by the Times Health Survey for Neurosciences.
SIMS holds NABH and NABL accreditation the Indian standards for hospital quality and laboratory quality respectively confirming that its clinical protocols, patient safety systems, infection control, documentation practices, and laboratory testing standards have been independently verified.
The Multi-Organ Transplant Programme
SIMS Hospital provides heart transplant, liver transplant, kidney transplant, and bone marrow transplant services within a multi-organ transplant programme that integrates surgical, medical, and critical care subspecialties under one institutional roof. This integration matters for bone marrow transplant patients because the procedure spans haematology, infectious disease, critical care, gastroenterology (managing GVHD-related GI complications), and nephrology (managing calcineurin inhibitor nephrotoxicity) all of which are available within SIMS's multi-speciality framework.
Blood Disorders That Require Bone Marrow Transplant at SIMS Hospital, Chennai
Bone marrow transplant is not a treatment for all blood disorders it is the specific treatment for those where replacing the bone marrow and immune system is the only pathway to cure or long-term disease control.
Acute Leukaemias
Acute Lymphoblastic Leukaemia (ALL): The most common haematological malignancy in children and a significant diagnosis in adults. Standard-risk ALL is treated with chemotherapy alone in most cases. High-risk ALL defined by certain cytogenetic abnormalities, high white cell count at diagnosis, slow initial response to chemotherapy, or minimal residual disease positivity after induction requires allogeneic bone marrow transplant in first complete remission to achieve the best long-term outcomes.
Acute Myeloid Leukaemia (AML): Most adults with AML who achieve complete remission are candidates for consideration of allogeneic transplant, based on cytogenetic and molecular risk stratification. Adverse-risk AML (monosomy 7, complex karyotype, TP53 mutation, FLT3-ITD without NPM1 mutation) has a high relapse risk with chemotherapy alone, making transplant the standard consolidation approach. Intermediate-risk AML with a matched donor is similarly treated with transplant in many national and international guidelines.
Aplastic Anaemia
Severe aplastic anaemia (SAA) is a life-threatening bone marrow failure where the immune system destroys the haematopoietic stem cell pool. For patients under fifty with a matched sibling donor, allogeneic bone marrow transplant is the first-line treatment, producing long-term cure rates exceeding 85 to 90 percent. For patients without a matched sibling, immunosuppressive therapy with anti-thymocyte globulin and cyclosporine is used first, with transplant from a matched unrelated donor reserved for refractory cases.
Lymphomas
Hodgkin Lymphoma: Relapsed or refractory Hodgkin lymphoma after first-line chemotherapy is treated with salvage chemotherapy followed by autologous stem cell transplant. Autologous transplant uses the patient's own previously collected stem cells, avoiding GVHD and producing cure in 40 to 50 percent of relapsed cases.
Non-Hodgkin Lymphoma: Relapsed diffuse large B-cell lymphoma (DLBCL), mantle cell lymphoma, and peripheral T-cell lymphomas are treated with autologous or allogeneic transplant depending on histological subtype, disease status at transplant, and donor availability.
Multiple Myeloma
Multiple myeloma is treated with novel agent induction (bortezomib, lenalidomide, dexamethasone) followed by autologous stem cell transplant as consolidation in eligible patients. Autologous transplant for myeloma does not cure the disease but significantly deepens remission, extending progression-free survival by two to three years compared to standard chemotherapy without transplant.
Myelodysplastic Syndrome (MDS)
Intermediate-2 and high-risk MDS by IPSS-R scoring carries a high risk of transformation to AML and has a poor prognosis with supportive care alone. Allogeneic bone marrow transplant is the only potentially curative treatment for higher-risk MDS.
Thalassaemia and Sickle Cell Disease
For children with transfusion-dependent beta-thalassaemia and a matched sibling donor, allogeneic bone marrow transplant is a curative option, eliminating the need for lifelong transfusions. Transplant outcomes in thalassaemia are best in young, well-chelated, low-risk patients (Pesaro Class 1 to 2). Sickle cell disease is increasingly cured by allogeneic transplant in appropriately selected patients with a matched donor.
The Bone Marrow Transplant Procedure at SIMS Hospital, Chennai
Undergoing a bone marrow transplant requires high-precision hematological protocols alongside advanced infection control and continuous supportive care. At SIMS Hospital in Chennai, the BMT unit delivers tailored cellular therapies designed to treat complex blood disorders, manage graft-versus-host disease (GVHD) risks, and ensure safe engraftment in HEPA-filtered cleanrooms.
Types of BMT Performed
SIMS Hospital's BMT programme covers the three main transplant categories:
Autologous BMT: The patient's own stem cells, collected before high-dose conditioning chemotherapy and cryopreserved, are reinfused after conditioning. Used for lymphomas, multiple myeloma, and selected AML cases. No GVHD risk. Infection risk concentrated in the neutropenic nadir period and resolves relatively quickly after engraftment.
Allogeneic BMT (Related Donor): Stem cells from a HLA-matched family member, most commonly a sibling. Carries GVHD risk requiring immunosuppression. Used for high-risk leukaemias, aplastic anaemia, MDS, and thalassaemia. For international patients, the accompanying family member who is the donor must undergo evaluation and the donor harvest procedure in Chennai during the same hospital admission.
Haploidentical (Half-Matched) BMT: When no fully matched sibling is available, a parent, child, or half-matched sibling can donate using post-transplant cyclophosphamide (PTCy) protocols that dramatically reduce GVHD rates. This has expanded donor availability significantly for patients without a fully matched sibling.
The Conditioning Regimen
Before stem cell infusion, the patient receives a conditioning regimen of high-dose chemotherapy (myeloablative or reduced-intensity depending on age, fitness, and disease) to eliminate residual disease and suppress the immune system sufficiently to allow the donor stem cells to engraft. This conditioning phase produces the neutropenic nadir the period of maximum infection risk.
Hospital Stay Duration
Based on confirmed hospidio com data and standard BMT practice: the hospital stay for bone marrow transplant covers the pre-transplant conditioning period (approximately one week), the transplant itself (day zero), the neutropenic nadir and early engraftment period (typically two to four weeks), and post-engraftment monitoring before discharge (approximately one week). Total hospital stay is typically twenty-five to forty days. Total in-India stay for international patients before return travel clearance is fifty to sixty days, covering the hospital admission plus post-discharge outpatient monitoring.
Infection Management During BMT at SIMS Hospital, Chennai
The most critical period of bone marrow transplant is the neutropenic nadir the ten to twenty-one days after the conditioning regimen when the absolute neutrophil count approaches zero and the patient has virtually no immune defence. SIMS Hospital's advanced ICUs, modular operating theatres, and blood bank with comprehensive apheresis capabilities support the infection management requirements of this phase.
SIMS Hospital Blood Bank offers comprehensive transfusion services with state-of-the-art collection, processing, and apheresis of blood and its components directly relevant to BMT patients who require irradiated blood products, platelet transfusions, and apheresis procedures throughout the transplant admission.
The infection management protocol for BMT patients at SIMS Hospital, Chennai covers:
-
Antimicrobial prophylaxis: fluoroquinolone antibacterial, antifungal (fluconazole or posaconazole depending on mould risk), aciclovir antiviral, trimethoprim-sulfamethoxazole for PCP prophylaxis
-
CMV monitoring and pre-emptive therapy for allogeneic transplant recipients
-
HEPA-filtered isolation during neutropenic nadir
-
Central line care bundles and neutropenic diet protocols
-
Daily ANC monitoring with G-CSF support to shorten the duration of neutropenia
