Question: Five years ago I was diagnosed with Stage 4 Metastatic Squamous Cell Lung Cancer. Prior to the diagnosis I was diagnosed for 1 and 1/2 years with Boop (a wrong diagnosis). Do it's been now 6 1/2 years. I have 3 small lymph nodes; pre and para trachia, whose size has not changed in over a year and the SUV fluctuates from 6.6 to 11.7. The last Pet Scan showed the 11.7 decreased to 8.3. My radiation and chemo Oncologist don't know "what is in my chest". Becuase of previous radiation to that area any type of biopsy is NOT possible. What are your thougths regarding this "unusal" finding?

Brief Answer: Nothing to worry, needs regular follow-up Detailed Answer: Hi, There is no evidence to treat the disease based on SUV, even it can be false positive. Moreover, the SUV can vary depending on your blood sugar and body metabolism. It’s good to hear the size of the lymph nodes have not changed over the time. As the biopsy of the node is not possible, you need to be on regular follow-up with your doctor for any increase in the size of the lymph nodes or primary lung lesion, for early diagnosis of progression of disease and treatment.

Hi Dr. XXXXXXX I have been told by both my Oncologists that my Squamous cell CA of the lung is a "different cancer" because it is INDOLENT. Is it likely that previous chemos have caused the cancer to mutate and that the nodes have now become Carcinoid Cancer Tumors? Both of my Oncologists told me that my Stage 4 Squamous Cell Lung CA was a "differnt" cancer. They said it was Indolent and that I could live a long time like that. Is it possible that 26 chemo infusions could have caused my cancer to mutate and become Carcinoid Cancer?

Brief Answer: Unusual to cause mutation Detailed Answer: Hi, Squamous cell lung CA behaving so indolent is very unusual, Still rarely possible. According to me it is unlikely the previous chemo infusions would have caused mutation to carcinoid. Either it could be a spread of squamous CA or a separate coexisting carcinoid. For both you need to be regular followup to diagnose the progression of disease early. Hope this helps. Regards

I have had black flecks, about the size of pepper or larger, in my urine for several months. The Dr. tested it and found no infections, no blood in urine, creatinine levels are fine. I have many other symptoms similar to those listed for carcinoid syndrome, like peripheral edema and neuropathy, abdominal cramping (esp. if I have even 1 drink of alchohol). Do you think the black flecks could be related?

I have had surgery to remove cancer from the right ascending colon (stage 1) and a neuroendocine carcinoid tumor from the small intestine (stage 3) 2 out of 14 lymph nodes were found. I have changed my diet to low-fat, organic, no red meat, low dairy and 6 to 10 vegetables a day. What vitamins and supplements would you advise to help keep the cancer from returning?

Two years ago I had a lot of symptoms similar to those of carcinoid syndrome: sudden spike in blood pressure 170/105 (my blood pressure has always been low 110/70), dizziness, confusion, chills, that lasted anywhere from 15 minutes to 1 hour. I went to the emergency room a couple of times, I saw different specialty doctors (neurologist, endocrinologist, cardiologist, etc..),

all my blood tests were O.K. with the exception of serotonin in urine, which was highly elevated 2 times. For more than a year I was fine, but one evening I got another spell that sent me to the ER again. This happened in February of this year. Since then I have been sick with the same symptoms every week. All my blood tests are fine and the serotonin is OK. I don't know what to do anymore and what specialist to see. Please advise.

Thank you

These fevers are accompanied by extreme weakness- and are again,recurrent- Can you help me understand the meaning of these symptoms..."tumor fever" has been mentioned...What is this?
