I cannot recall a time when I was this upset with myself. I’m not a doctor, but I feel my background should have allowed me to piece together the clues and help come up with a differential diagnosis much earlier. The perfect opportunity to participate in my healthcare by joining in the discussion and raising the right questions.
Lorie and I made a trip to Memorial Sloan-Kettering Cancer Center’s (MSKCCs) urgent care center last Tuesday (11/6/18). This was due to a fever and breathing difficulty both after going up/down stairs and following coughing episodes. Consider what was known at the time:
- X-ray at urgent care suggesting pneumonia
- Shortness of breath
- Non-productive cough
- Low-grade fever
- History of radiation therapy to lungs in late July/early August
Pneumonia is a bacterial infection that inflames the air sacs in one or both lungs, but a subsequent CT scan and blood work didn’t confirm. Nonetheless, to be safe and in the absence of any other condition, I was prescribed one week’s worth of the broad spectrum antibiotic levofloxacin (Levaquin®) and instructed to follow-up with my oncologist.
During the following week, all of the symptoms persisted. Between the breathing issues and fever, I didn’t feel like doing much other than resting on the couch all day and writing. Thankfully, I did manage to rally for an early birthday barbeque celebration this past Sunday. Then again, perhaps I jinxed myself by celebrating and posting early! Right, @23aloha? 😉
Aside from the aforementioned, recall that I’ve been suffering from back pain due to the progression of cancer to the spine. In early October, I met with a neurosurgeon at MSKCC in advance of receiving targeted radiation to two areas of my spine. To help prevent or minimize the pain flare that is common following radiation treatment to the skeleton, the neurosurgeon prescribed a steroid (dexamethasone).
Among other side effects, patients who are on steroids for three-weeks or longer are more susceptible to infections than are healthy individuals per the product prescribing information. After finishing radiation treatment to my spine on October 18th, I inquired with my health care team at MSKCC and began gradually reducing my dexamethasone dose to zero beginning on November 1st and finishing on November 6th (hint: day of my trip to urgent care, didn’t seem relevant at the time).
As referenced in my prior post, I’m not a big “birthday” person, but I was looking forward to celebrating my 50th milestone this past Monday. I hoped that the antibiotic would work and I’d be feeling somewhat better by then. No such luck. In general, I felt worse that day, and by the evening my temperature jumped to 101.9 Fahrenheit. No restaurant celebration or interest in my favorite ice cream cake (Figure 1). I took two acetaminophen, which brought the temperature down, and made an appointment the next afternoon to see my oncologist, Dr. David Pfister, and Nicole Leonhart, ANP, RN.
Of course, it wouldn’t be a commute between home and NYC without experiencing some significant delay. This time, a tugboat struck the Portal Bridge and we were held for close to an hour as the bridge was inspected for safety. We arrived at our appointment an hour late, but MSKCC was very accommodating.
After reviewing a new chest x-ray, my medical team offered a differential diagnosis of radiation pneumonitis based on empirical evidence. As soon as I heard the words, it made perfect sense. How could I have missed that! I knew radiation pneumonitis was a potential risk.
Radiation pneumonitis and pneumonia share many clinical features, including inflammation of the lung(s). Radiation pneumonitis is one of the most common toxicities of stereotactic body radiation therapy (SBRT). Most cases are either asymptomatic or manageable, with the reported rates of symptomatic radiation pneumonitis after SBRT range from 9% to 28%. However, most patients develop late pulmonary toxicity characterized by localized pulmonary fibrosis (scarring) in the region receiving the high-dose.
Sure enough, the suspicious areas on my chest x-ray correlated almost exactly with the areas targeted with SBRT over the summer. The sudden appearance of symptoms corresponding with tapering of the prior steroid dexamethasone also provided an important clue. It is likely the steroid meant to address potential bone pain flare issues was also treating the radiation pneumonitis. When I stopped the dexamethasone, the radiation pneumonitis was left untreated and suddenly became symptomatic. Ta-da!
The good news is that with adequate steroid treatment, most patients achieve complete recovery from their symptoms. As a result, I was prescribed an initial two-week supply of another steroid (prednisone). But a diagnosis of pneumonitis does increase the risk of developing subsequent pulmonary complications, including fibrosis, a permanent scarring of the lungs.
While it wasn’t a perfect birthday in the traditional sense (whatever that even means), I prefer to focus on the fact that Lorie, Rosie, and Megan (and the zoo!) were with me on this 50th milestone, and that the recent symptoms weren’t due to further cancer progression (my initial concern) but rather a manageable radiation treatment side effect. Honestly, that is the best gift I could have received.
I would be remiss if I didn’t also acknowledge how important all of the happy birthday calls, texts, gifts, and social media posts were to me. It is one thing to hear from family and friends, but some messages from people I’ve never met in person were also truly lovely and brought a smile to my face. I do read EVERY post! So, to everyone who took time out of their day to acknowledge my birthday—thank you from the bottom of my heart!
