Cityview, that is a great paper. I have read it before, but it's good to re-read it again.
Figure 1 is a good summary for quality-of-life following which of the three choices are taken. The overall ranking is that with regards to quality of life, Observation comes first, Radiosurgery comes second and Microsurgery comes last.
I love the paper's conclusion, at the end of paper (with my emphasis underlined):
Overall, the HRQOL differences following observation, microsurgery, and SRS are small. The diagnosis of VS, rather than treatment strategy, most significantly impacts patient quality of life. Therefore, further improvements in patient counseling regarding realistic long-term expectations of disease, as well as offering pre- and posttreatment psychosocial support, may provide the most impact on HRQOL improvement for patients with VS.
Since a significant number of tumors do not grow after the time of diagnosis, and because intervention does not appear to confer an HRQOL advantage over observation, small- and medium-sized VSs should be initially observed, while active treatment should be reserved for patients with unequivocal tumor growth or intractable symptoms that are amenable to treatment. As disease-specific HRQOL outcomes following SRS appear to be minimally better than microsurgery, we believe that SRS should be offered to those with growing tumors and minimal symptoms, while microsurgery should be considered for patients with symptoms associated with mass effect, enlarging cystic tumors, or in cases of patient preference. Moving forward, studies assessing HRQOL in VS patients should prioritize use of validated disease-specific measures, such as the PANQOL, given the significant limitations of generic instruments in distinguishing between treatment groups and tumor versus nontumor subjects.
It looks like those of us in the Observation group is the way to go unless there is "unequivocal tumor growth or intractable symptoms". My tumor has not grown in the 2-and-a-bit years since diagnosis and my symptoms are mild.
