The Thymic Disorders Program in the Massachusetts General Hospital Division of Thoracic Surgery has extensive expertise in treating the full spectrum of thymic conditions—from the most common to rare and complex thymic disorders.
Mass General has been a longstanding leader in the field of thymoma surgery. Our experience gives us a distinct advantage in understanding this rare condition and how best to treat it based on the patient's circumstances.
As part of our standard of care, we follow patients over the long term to monitor for possible recurrence. Where appropriate, we collaborate with thoracic oncology specialists from the Mass General Cancer Center, including medical oncologists and radiation oncologists, to treat patients with thymoma or thymic carcinoma. Our multidisciplinary approach to care enhances our ability to evaluate and treat our patients.
Our surgeons are highly experienced in treating the following thymic conditions:
Our program also treats extremely rare conditions involving thymic cysts, thymolipoma and thymic carcinoids.
Patients with myasthenia gravis (MG) initially have their condition diagnosed and medically stabilized by a neurologist, who then refers the patient to our surgeons. The surgeon first arranges for the patient to have a computed tomography (CT) scan to look for a potential thymoma as MG has about a 25 percent chance of being associated with a thymoma. Based on the findings of this test and other factors, we work with the patient to determine the most appropriate surgical course of treatment.
Our division's physicians are highly skilled in performing transcervical thymectomy and video-assisted thoracoscopy (VATS), two minimally invasive procedures for thymus removal. We also perform standard open (i.e. transsternal) procedures. Recently, robotic-assisted minimally invasive thymectomy has been introduced as an additional option for selected patients. We have an excellent track record with all techniques in terms of patient outcomes.
Following surgery, the patient’s neurologist will provide ongoing follow-up, which may include medication management for any muscle weakness.
Our surgeons typically can diagnose thymoma by reading a CT scan. A PET/CT scan or MRI may also be necessary. Smaller tumors often are excised via surgery alone, which is a quick and effective approach.
Thymomas that are large and/or locally advanced require more complex treatment. We may begin by performing a fine-needle aspiration (FNA) biopsy, in which we sample cells from the tumor using a very thin needle.
Depending on the biopsy results, the patient may undergo chemotherapy or chemoradiotherapy and then surgery—all of which we coordinate with our thoracic oncology specialists at the Mass General Cancer Center. We usually perform open transsternal procedures in these cases, as we believe they produce better outcomes than minimally invasive approaches
Thymic carcinomas are similar in nature to thymomas, but more advanced. These usually require chemotherapy or chemoradiotherapy before surgery.
Chance of recovery and treatment options for thymoma and thymic carcinoma depend on:

Mass General has been treating and researching thymic disorders since the 1950s. Today, members of our division are recognized nationally and internationally as experts on thymoma and other thymic disorders. We have published many significant papers on thymoma. View publications

Myasthenia gravis (MG) is a complex, autoimmune disorder in which antibodies destroy neuromuscular connections. This causes problems with the voluntary muscles of the body, especially the eyes, mouth, throat, and limbs.
